BenGoldberg So I have a question, which is perhaps a bit mad. I know that one of Rakudo's backends is the jvm. I know that android apps must be written in java (or at least, be made of jars containing java class files). So, can rakudo run on an android phone or tablet? 00:52
BenGoldberg wonders if he might have accidentally stumbled onto perl6's "killer app" ;)

BenGoldberg Ha, that's waaay beyond my skill level! 00:55
Now, if someone else created a rakudroid deployment deployment system, I'd be happy to write a game of tetris in perl6 to play on my phone ;) 00:56

perigrin so one of the hiccups is that android doesn't use the JVM 00:58
00:59 evalable6 left, evalable6 joined
perigrin however castaway got pretty far at one point cross-compiling perl5 for the NDK APIs on android ... so someone might get further getting MOAR via the NDK. 01:01
01:08 cpage_ joined
BenGoldberg Even though android does not literally use a jvm for itself, all apps which run on it must use java bytecode, which, as they get loaded, are transparently compiled into dalvik bytecode or native instructions. 01:16
sacomo hi all, question about methods using `is export`, is there any way to make their class attributes / self. available from the exported method? bar() instead of Foo.bar() 01:19

lookatme sacomo, what do you mean, a singleton ? 01:32
And I think self is can only using inside class . :) 01:33
sacomo I read somewhere that we can use "method foo() is export {}" and access foo like with exported subs. Not sure if that is possible. I know we can export subs from inside a class, but we don't have access to self. from those subs. 01:34
I could be wrong though. I am usually wrong.

AlexDaniel piojo: heh, yeah, but it is (as confirmed above). sha^ gives a parent of that commit, and on a commit before there's no problem 03:13

AlexDaniel I think the issue comes from this line: + my Pair @arg-help; 03:13

piojo AlexDaniel: Seems like I should do a more difficult bisect, manually applying 22b4ef05b to each revision and seeing if that can trigger the underlying problem 03:19
AlexDaniel piojo: sorry, what for? :) 03:20
piojo AlexDaniel: because it seems to me that 22b4ef05b isn't the real problem. It's more of a diagnostic tool. 03:21
AlexDaniel piojo: if you really want to, you can try reverting 22b4ef05b on HEAD
03:21 ctilmes left
AlexDaniel piojo: and that will definitely make the problem go away 03:21
03:22 someuser left
AlexDaniel piojo: and then, you can try changing “my Pair @arg-help;” to just “my @arg-help;” 03:22
and that'll probably make the problem go away, at least if my hypothesis is correct :)

piojo AlexDaniel: Do you have a more specific guess about what the underlying problem is that that change would help with? 03:22
BTW, the problem is also showing itself with Array[CustomClass], not just Array[Pair] 03:23

AlexDaniel piojo: so using Int instead of Pair is OK
piojo AlexDaniel: right, Int works. I haven't explored which types of classes show the problem. 03:31
the only big difference I see is that Int is (Cool) and custom types and pairs aren't 03:32
AlexDaniel piojo: I don't have an educated guess on why exactly it is behaving like this :) 03:33
03:34 ufobat_ joined
piojo AlexDaniel: That's why I think a more labor-intensive bisect could help, if I can force the bug to reveal itself prior to the 22b4ef05 commit. Though that might not be possible if the code changed too much. 03:34

AlexDaniel piojo: not sure I understand. You have a non-intermittent bug and you know which commit caused it, what are you looking for now? 03:38
03:41 silug left
piojo AlexDaniel: are you suggesting a workaround for me, or a fix for the next rakudo release? If we changed this in rakudo, it seems like it would be sweeping a problem under the rug, and it could come back when a different core function uses a parameterized array. 03:47
Though the situation can be improved if I add a unit test for this
we can hope the next time this occurs, it will do a better job of illuminating whatever is wrong in nqp or moarvm
AlexDaniel piojo: am suggesting a rakudo fix, yes. Would be great to have tests that go over a bunch of types (not just Pair)
piojo AlexDaniel: my concern is just this: something is wrong with the type system, and 22b4ef05 did not cause it, since there's no error in that commit. I will try to find the underlying bug, and if I can't, I'm okay with a workaround 03:49
AlexDaniel piojo: ok, a way to do it would be to apply 22b4ef05 to some old revisions (e.g. 2015.12) and see if it breaks the same way there 03:55
piojo AlexDaniel: yes, that's my intention. It doesn't apply cleanly, so by-hand changes will be needed. I'm not sure whether it'll succeed, but it's worth the try. 03:56

perlbot chenyf pasted a new file at f.perlbot.pl/p/3jg9le -
thou Does anyone know if there's current activity refactoring Pod::To::* modules to use a common framework, and to fix outstanding [POD] bugs in Rakudo? I've been making some tweaks to Pod::To::Markdown, and am wanting to get rid of warts rather than paste over them.

piojo AlexDaniel: it fails on all real strings 04:55
04:56 TimToady joined
piojo I'll fix it if the test try { $_ == $_ } is the right one. (Also, it needs to eliminate "" because "" is castable to a string) 04:56

04:58 cpage_ joined
piojo AlexDaniel: Nice! I didn't realize .Numeric returned Failure 04:58
AlexDaniel piojo: why does it need ($term ~~ /\d/) check at all? 04:59
piojo still, I don't see why we need regexes for this
I didn't write it!
it just needs to check that the string isn't empty.
05:00 cpage_ left, mcmillhj joined 05:01 Actualeyes joined

AlexDaniel piojo: what about: defined $term.Numeric 05:02
or more explicit $term.Numeric !~~ Failure
explorer: not that I know of 05:03
piojo AlexDaniel: both seem fine. Is Str.Numeric being Failure part of the spec, or an implementation detail? 05:04

piojo I don't disagree with that, actually. It seems like a source parse needs to be more thorough than a mere string conversion. 05:09
thou explorer, you could use .Supply and specify a :quit routine that does nothing
and Supply.grep() and .head() might help, too 05:10
AlexDaniel piojo: these are the tests: github.com/perl6/roast/blob/8da277....t#L83-L91
piojo: I wish it was tested more thoroughly, but maybe it is in other files 05:11
thou Or maybe :quit() doesn't work that way, I'm not positive....
05:11 explorer left
AlexDaniel piojo: whitespace characters being turned into 0 is weird :( 05:12
thou hrm, looks like I jumped the gun on that solution, I didn't read .Supply() description clearly
piojo AlexDaniel: and 'i' and 'e' can be Numeric but not '½'. That seems inconsistent 05:13
No, my mistake
I wasn't using the string in that test
AlexDaniel m: react { whenever Supply.merge: (Promise.in(3), Promise.in(2))».Supply { say $_; } } 05:15
camelia True
True
AlexDaniel maybe something like this can be hacked to do what's needed? 05:16
m: react { whenever Supply.merge: (Promise.in(3), Promise.in(2))».Supply { done if $_; say ‘hello’ } }
camelia ( no output )
AlexDaniel m: react { whenever Supply.merge: (Promise.in(3), Promise.in(2))».Supply { say ‘hello’; done if $_ } }
05:16 mcmillhj joined
camelia hello 05:16
AlexDaniel piojo: so that's why the regex check is there :) 05:17
piojo AlexDaniel: yep. But we're looking at this the wrong way: according to every other part of the test, this is a check about whether a string is a valid perl6 number. It's wrong to exclude '' as being a number 05:19
05:19 angelds joined
piojo If "1.3e+12" is a number, then "" should be considered a number as well 05:19

piojo .ask lizmat Would you say it's a bad idea to use Pair as a member in a Set (or check $pair ∈ @array)? Because it seems awkward that Pair.WHICH is sometimes static (Pair.new(1,2)) but sometimes dynamic (Pair.new($a,2)). The ambiguity makes causes hard debugging since $foo !== EVAL($foo.perl), but EVAL($foo.perl) === EVAL($foo.perl) 07:13

timotimo if you go with an equality function, you're suddenly going far up in complexity cost of operations
checking for presence of a single item in a set is amortized O(1), but if you have an equality function, you have to check against every entry of the set, which is O(n)
if you want to get the union or intersection or whatever of two sets, you're looking at O(m*n) instead of O(m+n) 15:18

perlpilot As a corollary to that I guess, we have some code at $work where the author came from a Java background and put type constraints on everything and over the last several months we've been removing type constraints where they were over-zealous because it was causing problems as things were refactored or new features were added. 17:06

Ulti on twitter there was a nice example between python and perl6, reverse the order of digits in a number P6 1234.flip Py int(str(1234)[::-1]) I know which of those two is easier to teach to someone without having to get into what type is immediately
comborico1611 It is a balance between quickly being able to do something versus understanding how computer programs work. 17:25
perlpilot comborico1611++ for the advent article btw. My only suggestion would be to shorten the next one ;)
Ulti comborico1611: its more different languages pick different abstractions of how programs work, none of it is how a computer works 17:26

Ulti even assembly now isnt how a CPU works
comborico1611 Ulti, true. But some programming languages do much better at that than others.
Ulti given the whole thing is running a unix on the inside with a web server...

comborico1611 perlpilot, I really had to go into the details of the book review because I didn't want to just say things and not have it backed up, and I already done the work of meticulous notes. 17:27
And I felt I really had to explain how I'm not like most computer programmers. If you can even consider me a computer programmer. 17:28
Ulti if you tell computers who's boss you are a computer programmer 17:29
comborico1611 heh
Ulti I think writing a blog post about programming probably qualifies you fairly immediately
17:29 araujo joined, AlexDaniel joined
comborico1611 But you're welcome, perlilot, it was a good opportunity to be able to right such an article for you all. 17:30
Haha, you kid.
Ulti no really
perlpilot comborico1611: I agree with Ulti here.
Ulti the idea of someone having imposter syndrome about being a programmer is kind of fun 17:31
17:31 albongo joined
comborico1611 Heh. Time will tell if i am. 17:32
Ulti someone should make a webpage where you accidentally write a program on the landing page to a test to find out if you're a programmer and you just immediately pass
perlpilot I've known many people who primarily identify as "journalist" or "scientist" or "mathematician" or "geographer" or "surveyor" or "physicist" .. etc. who are nevertheless "computer programmers"
It's just that they come at programming from a different need or mindset than those you'd call "CS types" 17:33
comborico1611 I see. That makes sense. 17:34
perlpilot In fact, even though I got a degree in CS, I think I know more people who are *not* CS types, but are still programmers.

hahainternet is there a way to use non string keys for a hash in a way that doesn't require overriding the WHICH method? for example, lists? 18:38
18:39 darutoko left
timotimo subclass the hash and implement the stuff there? :S 18:44
hahainternet timotimo: :/ that is a bit of a wart 18:46
looks like it'd be better to define custom list type and make it a 'value type' by p6's defs?
timotimo that's also possible, but i thought that falls under "overriding the WHICH method" 18:47
[Coke] what's wrong with the existing non-string-key hash variant?
hahainternet [Coke]: it uses ===, and so (1,2,3) === (1,2,3) is false 18:48
timotimo: ah, yeah my fault for constraining that
i should have asked for the nicest way, ideally not overriding WHICH
timotimo time to bring parcel back %) 18:49
hahainternet doesn't get it ☺
timotimo it was a thing that existed before the GLR
think of it as "lazi decision whether to flatten or to structurize listy things"
hahainternet roger 18:50
well i would throw a vote behind immutable lists testing equality based on values
ie 'value types'
but i don't know what issues that would cause
and i'd appreciate advice on the best way to implement my own type
MasterDuke hahainternet: you couldn't use a set instead of a list?
timotimo List is doing double-duty for lazy lists as well, so there'd have to be a lot of care taken with regards to WHICH on lazy lists vs fully reified lazy lists etc 18:51
hahainternet MasterDuke: the same issue occurs doesn't it?
hmm, apparently not
lists and sets are unfortunately not synonymous
perhaps a Tuple type? ;)
timotimo yeah, sets are lists minus ordering and multi-containering
DrForr waves at MasterDuke 18:52
hahainternet i assume i should be able to construct this as List but Tuple or similar if my Tuple type implements WHICH based on values? 18:54
MasterDuke DrForr: hello hello. btw, do you know if your talk is online yet? since i got in late i missed it
DrForr Dunno. 18:55
18:55 rindolf left
DrForr Let me check. 18:55
timotimo hahainternet: and take extra care to decontainerize everything and anything that comes in
18:55 wamba joined
timotimo and not allowing anything mutable in it 18:56
hahainternet the mutable part is certainly important
but as long as i called WHICH on any container, that should be fine right?
i suppose given it returns basically plaintext
that's not safe
timotimo well, if you want to have something compare truthfully against something you put into a hash, you'll have to be able to produce the same WHICH
DrForr I don't see 2017 up at all yet. 18:57
It wsn't much of a talk; I was on early enough that I just did a brief routine and then got some audience participation going.
hahainternet interesting that sets seem to encode their contents in some form
-> Set.pm 18:58
(in calls to WHICH i mean)
timotimo it's a sha1 hash
hahainternet roger, i shall adopt the asme
as that is safe
timotimo zefram found a million different ways to create things that are very much not the same, but have the same WHICH
basically WHICH-injection attacks :)
hahainternet indeed, which is quite a serious issue 18:59
but hashing the contents makes perfect sense
and is what's used elsewhere safely, so that answers my q
lizmat FWIW, I would be in favour of List.WHICH as a value type if it doesn't have any containers 19:03
[Coke] what's wrong with the existing non-string-key hash variant? 19:06
(oops)
lizmat ? 19:07
hahainternet lizmat: can you elucidate on the issue with containers? couldn't it 'simply' call WHICH on them also and hash them?
lizmat hahainternet: what we don't want is that the .WHICH of an object changes over the lifetime of the object 19:08
hahainternet ah, so it should be memoizable etc
i'm with you
lizmat if you would call .WHICH on it like that, you would be able to change either the content of the object without .WHICH changing (it being memoized) 19:09
19:09 cdg left
lizmat or change .WHICH if it was not memoized 19:09
either one of those are bad
hahainternet roger, it's semi irrelevant for my use case at the second but i understand why it's an issue now
19:09 cdg joined 19:10 rindolf joined
hahainternet i would say a Tuple type or similar would be a good match there, a List which cannot store containers? I don't know the fine grained details though ☺ 19:10
lizmat now, List.WHICH not having a value type .WHICH is really an optimization issue

DrForr Design question - I'm doing a rewrite of Pod::To::HTML so that it can hopefully be subclassed. The core is an object tree of Pod::Heading.new( :content(Pod::Item.new(...)) and so on. I'm writing one multi method visit(Pod::Item $node){} per class that Pod::To::RawHTML's children can subclass and pervert at will. Short of trying to injet a 'walk' method into the Pod::* class hierarchy, is there a better way to do what I"m after? 19:21
It's not too fragile in that I can have a multi method visit( $node ) {} that catches stuff I'm not aware of, but I"m ondering if there's a better way. 19:25
19:25 thou joined
hahainternet seems i can't use 'but' as it creates some sort of implicit middle type with its own WHICH implementation 19:26
19:29 rindolf left
geekosaur that's its purpose 19:32
it's generating a class on the fly with the lhs's type and the rhs's type mixed in 19:33
timotimo i believe most which implementations will put their type name (longname?) in the beginning 19:34
and mixing in something will influence the type's name
m: say (1 but "foo").^name

thou tbrowder, I'm especially concerned with 114480, and the recently-"fixed" =Html as raw HTML changes, and Pod::Block::Named in general is not right, IMO. The Pod::Raw is what named blocks are supposed to be for. The things that are currently called named blocks shouldn't be, e.g. the current Pod::Block::Named with .name 'para' should be a normal Block::Para (core should join the lines together for us, that shouldn't be something Pod formatters are handling!). 20:09
tbrowder, I'm basing my "should" language on what S26 says, as I *love* S26 in all ways and think it's a flawless design which can never be improved upon. 20:11
Or, at least, the status quo is certainly no improvement on S26. Hopefully I can get assent on that much. ;-) 20:12
DrForr, there's a couple older branches in there attempting the same thing. I haven't dug into them, but Pod::TreeWalker is fairly complete. There's also an old branch of docs that uses autarch's Pod::To::HTML branch. It has a subclassed renderer IIRC that you might find interesting. 20:15
DrForr If you're woring with Pod::TreeWalker I'm happy with starting with that as a basis.
*working 20:16
hahainternet so from what i can tell, the | operator will change list contents into scalar containers of their content for all the invocations i have tried
including Captures, which is a bit odd
DrForr I admit I'm a touch surprised yet gratified to see autarch doing P6 work, helps ratify things a bit. 20:17

thou advent admins: it may be considered LTA to have an unanswered question from 2009 as the only comment on perl6advent.wordpress.com/about/ ? I think it'd be ethical to remove that comment, and would improve user experience IMO. 21:14
Also, I guess it is a reasonable question to have answered on the About page, too. :-D 21:15
tbrowder thou: i’ve taken a look at RT #114480 and a possible solution with what we have now with no grammar change, just all in src/Perl6/Pod.nqp and src/core/Pod.pm. It would invove adding attrs to the Perl 6 Pod::Block::Table class and could be backwardly compatible if need be. Otherwise, I would make each cell a pod formatting class.
synopsebot RT#114480 [open]: rt.perl.org/Ticket/Display.html?id=114480 [POD] Pod table cell contents should be parsed as para
thou tbrowder, I think incremental improvement is good. I am interested in making grammar fixes, but (especially if I'm doing it) those can take longer to work out. 21:17
hahainternet so, it seems that if you use a slip in List.new() it will containerise every element of that list, the only obvious reason i can see is perhaps that List's new Signature is **@things, and I believe that is coercing the slip (or Capture) to an array, enforcing the containers 21:18
tbrowder But before any of that happens I would like to see LLfourn’s PR merged (PR #651) to simplify twines 21:19
hahainternet when a function takes a capture, that doesn't seem to happen, although i don't know if captures destructure embedded lists 21:22
but i'd like some comment on whether this is correct behaviour, as it's certainly surprising
OVH seems to be having proper internet issues too so apologies if i don't reply promptly if anyone wants to comment 21:23
21:23 geospeck left
thou I've been thinking about creating a facade, maybe in userspace (i.e., Pod::TreeWalker, Perl6::Pod, or something) that takes the current parse and munges it with whatever hacks needed. E.g., to fix my pet peeve about named blocks, it would rewrite ::Named objects to ::Para or ::Heading or whatever is appropriate, etc. Then the user-facing tools (Pod::To::HTML, etc.) could be rewritten to use the facade whenever, and then as the grammar is fixed the facade 21:24
can be reduced until eventually it's just passing everything through. That would enable gradually fixing the parsing without breaking stuff too much, maybe. It sounds kind of baroque to describe it but I think it could be doable.

timotimo gist.github.com/tbrowder/5b639366a...28465d93e1 - tbrowder does that ring any bells?
tbrowder yep--i think the code is too ugly to handle at the moment...i'll report later if i have any trouble after clean up 21:58
timotimo which one was the line you stumbled upon ooc?

Morfent how come i can call idn2_to_ascii_8z(''), but trying to call idn2_to_ascii_8z('', 0) or idn2_to_ascii_8z('', 0, $code) throws X::Multi::NoMatch? hastebin.com/bogiqapepu.pl 22:03

timotimo does it get better if you make the proto's signature Str, $?, $? or something? 22:06
Morfent nope 22:07
timotimo and without a proto entirely? 22:08
Morfent Cannot use 'our' with individual multi candidates. Please declare an our-scoped proto instead 22:09
timotimo ah
ok, can you try "is export" instead of "our proto"
i.e. no "our" in front of the multis, either
tbrowder timotimo: looks like this line which was not within code brackets: "===SORRY!=== Cannot iterate object with P6opaque representation" 22:11
thou multi sub idn2_to_ascii_8z(Str $input, int32 $flags) {
("in:", $input, " flags:", $flags).gist;
}
say idn2_to_ascii_8z('HI', 0);
^ That fails, but remove 'multi' and it succeeds 22:12
with multi, Int works, but int32 doesn't 22:13
22:14 setty1 left
hahainternet lizmat: the behaviour seems the same to me after doing `rakudobrew build moar d80df073ada4d4bc3e32afc2d11f974122802698` 22:16
i'll see if i can figure out what i'm doing wrong tomorrow, thanks for looking though! 22:17
guess i should add a test
lizmat yes, pls :-)
tbrowder timotimo: even within ``` the line causes a failure.
Voldenet well, that's because Int isn't int32
m: multi sub idn2_to_ascii_8z(Str $input, int32 $flags --> Str) { "" }; idn2_to_ascii_8z("", 0); #fails 22:18
camelia Cannot resolve caller idn2_to_ascii_8z(Str, Int); none of these signatures match:
(Str $input, int32 $flags --> Str)
in block <unit> at <tmp> line 1
Voldenet m: use nqp; multi sub idn2_to_ascii_8z(Str $input, int32 $flags --> Str) { "" }; idn2_to_ascii_8z("", nqp::unbox_i(0)); #works
camelia ( no output )
DrForr There, did a subclassable renderer for the NAME, AUTHOR &c tags.

Zoffix hahainternet: along with lizmat's fix, you.d need `List.new: |@a.List` or `List.new: |@a».<>` 22:21
Morfent ah there we go 22:22
thanks thou
Zoffix Morfent: thou: Ints automatically get downgraded to int32 (or other natives) only for `only` routines. For multies, the match need to be exact (you'd need to pass a native to natives). So you'd either need an `Int` candidate or call with `idn2_to_ascii_8z('', my int32 = 0)` 22:23
hahainternet Zoffix: sorry i was getting some food, i am already doing that :)
the problem is that the list becomes containerised
Zoffix `idn2_to_ascii_8z('', my int32 $ = 0)`, I mean
hahainternet: for which code?
thou thanks, Zoffix++
hahainternet Zoffix: List.new(<1 2 3>».Int) or similar exhibits it
sorry i have to eat this before it gets cold, i'll be around briefly afterwards if i can help to resolve this 22:24
it seems using a capture works, but i don't know nqp well enough to help there
22:24 itaipu left
Zoffix hahainternet: you don't need ».Int part on it. You don't have containers in the first place and that will create a List with a single item in it: the other list 22:24
hahainternet Zoffix: i think i've tried every combination, so an example would be superb :) 22:25
Zoffix hahainternet: you're missing the slip
hahainternet: not sure what example to use, considering the code you showed above doesn't need a List.new 22:26
hahainternet m: say List.new(|<1 2 3 4>)[0].VAR.^name 22:27
camelia IntStr
hahainternet interesting
i get a different result locally
Zoffix hahainternet: did you build lizmat's commit?
hahainternet i thought so
22:27 itaipu joined
Zoffix hahainternet: perl6 -v 22:27
hahainternet i specified it to build moar, but i guess i'll go off and build it indivdualy
2017.10-4-g4fca94743 22:28
so i guess not :/
Zoffix hahainternet: that's over a month old
hahainternet yes, i guess rakudobrew did not switch correctly
Zoffix hahainternet: you didn't switch
It doesn't switch automatically, unless you just re-do `rakudobrew build moar` to re-build the head 22:29
22:29 kitsunenokenja left
hahainternet Zoffix: seems if you do 'build moar commitid' then do 'switch moard-commitid' it will say it is switching, but do nothing :) 22:29
that solves why that's happening though at least
doing a self-upgrade atm just in case 22:30
Zoffix hahainternet: works fine for me. Do you even need multiple versions of rakudo tho?
hahainternet Zoffix: probably not, moar-blead or just moar for including lizmat's commit?
22:30 cdg_ left
hahainternet or just moar commitid? 22:30
Zoffix hahainternet: just moar 22:31
huggable: sauce
huggable Zoffix, Install untested latest development version of Rakudo from source: github.com/zoffixznet/r#table-of-contents
22:31 cdg joined
Zoffix hahainternet: ^ or you can toss rakudobrew altogether and not deal with its quirks 22:31
hahainternet roger that, thank you
Zoffix hahainternet: anyway, that will fix `List.new(|<1 2 3 4>)[0].VAR.^name` for you. But that'd fail for very large lists 22:32
m: List.new: |(^10_0000)
camelia Too many arguments in flattening array.
in block <unit> at <tmp> line 1
Zoffix hahainternet: so you should consider coersing some other way. Like, just use .List coercer instead of List.new
m: (^10_0000).List
camelia ( no output )
Zoffix But as I've said, <1 2 3 4> is already a List. Not sure why List.new is needed.
hahainternet Zoffix: this was originally about creating a subclass that 'is List' but has a WHICH behaving as a value type 22:33
and degenerated into finding why suddenly my list was full of containers
Zoffix Ah
OK.

hahainternet that limit in flattening above seems exceedingly strange 22:35
i'd like to read why that's a thing 22:36
timotimo you mean "too many arguments in flattening argument list"? 22:38
hahainternet yeah, it seems like it means you can't really construct anything analogous to a list 22:39
tbqh it seems stranger than that, because why would there be an arbitrary limit on list flattening? 22:40
timotimo because of how arguments are passed
MasterDuke it's not really a limit on how big a list can be flattened (i believe), but on how many arguments can be passed to a function 22:41
timotimo m: say(1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1) 22:42
camelia 111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111
timotimo hm, that's enough
mspo 1, damn it!
hahainternet so i don't mean to sound negative, but doesn't that mean 'is List' can't actually work, as if your list is long enough, you can't construct your new type? 22:44
perhaps it just means you can't use the default List constructor :/

jnthn In general, though, avoid flattening huge numbers of arguments.
timotimo well, for other ops maybe
