rudi_s Hi. Is there a quick way to to if $a{$b}:exists and $a{$b}.foo eqv $bar { .. }? I don't want to retype $a{$b}. 00:28
raiph m: my $bar; say Nil eqv $bar 00:30
camelia rakudo-moar 1ef247: OUTPUT«False␤»
ugexe but his will autovivify on the second eqv i believe 00:31
raiph m: my %hash; %hash<a>.foo; dd %hash 00:33
camelia rakudo-moar 1ef247: OUTPUT«Method 'foo' not found for invocant of class 'Any'␤ in block <unit> at /tmp/Qs_ioOD1x2 line 1␤␤»

00:34 cdg left
ugexe i've been avoiding a non-existing problem, excellent 00:35
raiph rudi_s: use `.?` as the dispatcher instead of `.`
00:35 cdg joined
rudi_s raiph: Thank you. But this will break if $bar is e.g. a (Int) and $a is an Int hash, right? 00:38
raiph ugexe: those are generally the best type of problem to have but not if you're avoiding them
ugexe: :)
rudi_s raiph: Ah, it returns Nil for undefined values. So unless $bar is Nil, everything is fine? 00:39
raiph m: say Nil eqv Nil
camelia rakudo-moar 1ef247: OUTPUT«True␤»
00:40 cdg left
raiph m: say Nil.foo eqv Nil 00:40
camelia rakudo-moar 1ef247: OUTPUT«True␤»
raiph m: role MyNil {}; say Nil.foo eqv Nil but MyNil 00:41
camelia rakudo-moar 1ef247: OUTPUT«False␤»
rudi_s Hm. When does Nil occur "in normal life"? It's not the same as undefined (undef) in perl5, right? 00:42
raiph rudi_s: Nil represents an explicit absence of a value 00:43
rudi_s But that's different from unitialized or no value for the given key, right? 00:45
raiph rudi_s: correct
rudi_s Good. Thank you. Then that should work fine for me. 00:47
raiph rudi_s: One doesn't encounter Nil nearly as often as Any.
rudi_s: But perhaps more than the almost zero you're thinking.
rudi_s Hm.
So there's no short way which always works? I don't like solutions which may break sometimes. 00:48
00:56 maybekoo5 left
raiph rudi_s: Perl 6 is so beautiful. I'm still figuring stuff out. 00:57
ugexe maybe `if %x<a> andthen $_ -> $foo { say $foo.perl; }`, but its probably even more to type 00:58
raiph m: my $a = Nil; say $a
camelia rakudo-moar 1ef247: OUTPUT«(Any)␤»
timotimo ugexe: that looks syntactically wrong
$_ -> $foo ?
ugexe i meant $_.?foo -> $foo
raiph rudi_s: if one assigns Nil to a container, it resets the container's content to the default value. The default default value is Any.
timotimo that still looks wrong :) 00:59
TTIAR, no?
raiph rudi_s: Nil, which represents an absence of value, disappears when you assign it to things. So $bar won't be Nil 01:02
timotimo yeah, assigning Nil into a scalar variable will reset it to its default value
ugexe what is ttiar? 01:04
timotimo S99:TTIAR 01:05
what's wrong with synopsebot6?
Two Terms In A Row. A common error message often resulting from a missing "semicolon" between two "statement"s or putting an operator directly after a "sub".

timotimo S99:TTIAR 01:07
synopsebot6 Link: design.perl6.org/S99.html#TTIAR
rudi_s raiph: ugexe: Thanks for the explanation. I think for now I'll stick with the explicit check as it feels clearer to me (as perl6 beginner). 01:09
timotimo has someone suggested the "with" syntax? 01:10
that'll check for definedness rather than truthness
raiph timotimo: That was my first thought and it works too 01:11
timotimo ok
01:11 yeahnoob joined, bpmedley left
rudi_s timotimo: How can I extend that with a second condition? 01:12
raiph timotimo: but I felt there ought to be a nicer solution and I thought using `.?` fits the bill 01:13
timotimo can you show example code for what you mean, rudi_s?
rudi_s timotimo: if $a{$b}:exists and $a{$b}.foo eqv $bar { .. }?
(Or actually !eqv is what I need.) 01:14
01:14 bpmedley joined
timotimo ah. for that "with" probably wouldn't be the right thing 01:18
raiph timotimo: darn it, `with` was my first thought but please ignore the rest of what I said about it 01:19
ugexe `say "same" with my $xxx = %x<a> and $xxx.?foo !eqv $bar` i think
raiph (ie I don't know if it works or not)
timotimo ugexe: but the eqv will only ever return a boolean value and the with will check on that, rather than the %x<a> 01:20
rudi_s Something like this would be nice: $a{$b}:exists -> $_ and $_.foo eqv $bar { .. } - then I don't have to write $a{$b} two times.
raiph rudi_s: I don't understand why that's not just: use `.?` instead of `.` 01:21
timotimo you can use "my" inside that line, kind of like ugexe showed
rudi_s raiph: Sorry, eqv should be !eqv. 01:23
How would I combine that with ".?"? 01:24
raiph m: my $bar; my %a; %a<b> = 1; if %a.?foo !eqv $bar { ... } 01:25
camelia rakudo-moar 1ef247: OUTPUT«Stub code executed␤ in block <unit> at /tmp/1twOXXJaxX line 1␤␤»
timotimo raiph: you mean %a{$b}.?foo
raiph m: my $bar; my %a; %a<b> = 1; if %a<b>.?foo !eqv $bar { ... }
camelia rakudo-moar 1ef247: OUTPUT«Stub code executed␤ in block <unit> at /tmp/P6yb16sYjP line 1␤␤»
rudi_s m: my $bar; my %a; if %a<b>.?foo !eqv $bar { ... } 01:26
camelia rakudo-moar 1ef247: OUTPUT«Stub code executed␤ in block <unit> at /tmp/V_2pld3Jb0 line 1␤␤»
rudi_s I don't want to enter the block in this case. 01:27
timotimo ah, right 01:36
because Nil wouldn't eqv $bar

bioexpress Hello, is there a Perl6 signature which I could use to convey a native `wchar_t`? 09:49
CIAvash RabidGravy: Can you take a look at this question? irclog.perlgeek.de/perl6/2016-03-01#i_12121045 09:50
RabidGravy It's both :)
it should however be fixed for H::UA for the most recent 09:51
CIAvash Before, that message would just be printed but the code would work, now the code that uses H::UA dies. 09:53
RabidGravy what causes it is some code in the compile time mainline giving rise to a Failure, in the case of H::UA it is a "try require IO::Socket::SSL" that was in the mainline of the class 09:54
I moved it as late as possible
arnsholt bioexpress: Not currently, I think. Unfortunately
bioexpress Thx, than I have to wait a little bit. 09:57
CIAvash RabidGravy: You mean a fix was released?
arnsholt bioexpress: How much variation is there in how wchar_t is defined on various platforms? 09:58
RabidGravy Hmm I thought so but I may have made a mistake, it's in my local copy but not on GH :( 'ang on a sec 09:59
this will be why I'm not seeing it anymore but every one else is
CIAvash :)
bioexpress arnsholt: I don't know. I asked because I'ld like to use the ncurses `int addwstr(const wchar_t *wstr);` in Perl6. 10:00
arnsholt Right. If you'd like to get stuck in you can always just hardcode the relevant type for the platform you're working on 10:03
And then lobby one of the people working on NativeCall ATM to add a wchar_t type 10:04
bioexpress I will try it 10:05

partly Hi 10:43
I just search 15 minutes for an error. In the end it was an if $foo = -1 instead if $foo == -1. May be the compiler should warn one about this? Or is it a feature? 10:44
DrForr There are legitimate reasons to assign inside an 'if' expression. 10:45
partly DrForr: There were? (not arguing, trying to understand) 10:46
s/There/They/
jast in some languages a warning like that is generated only if the assignment is directly on the top level of the expression
e.g. if foo = 4 creates a warning, if (foo = 4) doesn't
DrForr Sure, think about do_stuff() if $index++; "Tested the index, now move on." 10:47
partly DrForr: Is $index++ not different from $index = -1? The first one is a function call, the second one is an assignment? 10:48
DrForr They're both assigning. 10:49
partly Maybe a similar warning like jast mentioned?
10:50 kjs_ joined
RabidGravy regarding the wchar_t thing, it would need to be implemented in NativeCall::Types, MetaModel::NativeHOW and the P6Int repr 10:50
DrForr Well, propose it, I suppose. I do it myself on occasion but usually find it quickly.
RabidGravy not so trick
partly DrForr: how do i propose something? Any manual on that? 10:51
DrForr Pull requests speak louder than words ;)
I wouldn't know though. Discussing it here can't hurt. 10:52
partly DrForr: ic :)
RabidGravy lots of places where you might want to test an assignment 10:54
if $a = something() { } is quite common 10:55
10:55 labster left
partly RabidGravy: yeah i see how this can be useful. 10:57
DrForr Worst case, rely on the old C trick of '1 == stuff()' :) 10:59
11:00 wamba joined
partly DrForr: TIL. thank you! 11:01
RabidGravy is there some web server module that a) won't output any headers at all if you don't ask it to, b) can support arbitrary request methods 11:02
DrForr Patience, Daniel-San :) 11:03
RabidGravy the icecast source protocol is a bit, er, special
DrForr Will Crust allow [] in place of the usual content-type?
RabidGravy well, HTTP::Server::Tiny always adds the Date and Server headers 11:04
DrForr Feature request of them, maybe? 11:06
RabidGravy and the source protocol don't work if you send anything other than a "HTTP/1.0 200 OK\r\n\r\n" in response to a valid SOURCE request
which is all a bit yuck 11:07
and it appears the client on receipt of that just splurges the data over the open connection 11:10
11:12 rurban joined 11:15 Guest22451 is now known as luiz_lha
RabidGravy the documentation alludes to modern servers using PUT but I haven't find a client that actually does that 11:16
11:17 johndau joined
Juerd 11:55 < RabidGravy> if $a = something() { } is quite common 11:17
Well, it used to be. And then we got: if something() -> $a { ... }
DrForr Well, Prancer accepts PUT but I don't know if the P6SGI layer does. I've had to rewrite the core because I found a problem in the URL mapping.
RabidGravy yes
Juerd So far, I haven't written a single "if $a = something() { ... }" yet, simply because I never wanted that $a to be scoped outside the block anyway. 11:18
(iirc)
RabidGravy well the HTTP::Parser thing will accept any old request method 11:19
Juerd So this does change my mind from not wanting that warning to really wanting it :)
Might even try to patch that myself
RabidGravy I'm relaxed about it, but I think it should be limited to constant values on the RHS 11:20
lizmat re: if $a = something() { } being quite common: yes, in P5 11:33
in P6 we can do: if something() -> $a {} 11:34
so perhaps a general warning for if $a = something *could* be in order in P6, pointing to the something -> $a alternative 11:35
ah, I see Juerd already made the point :-(
llfourn I don't think that should be a warning. You can legit reasons for not using pblock. 11:38
like not wanting a ro container and not wanting to write 'is rw'
or "is copy" rather 11:39
jnthn The "only warn if it's a literal on the RHS" may be a reasonable compromise
llfourn but people don't usually if literals :P 11:40

"callify" the default_value, it seems
lizmat yeah, which means adding overhead
jnthn Probably coping with a place where we may get a funk or may get a value and want it to be consistent
*thunk 13:48
tadzik it may make sense to call it if it's code, save it if not
unless it's meant to be lazy
jnthn It's rather hard to say without context ;)
tadzik ye :)
lizmat $rest ~= ' = { ... }' if $default;
it's about Parameter.perl 13:49
jnthn Hm
If it's a value we could actually .perl the value...
lizmat now, if $default were just a value, we could actually say: $rest ~= " = $default";
jnthn $default.perl() :)
lizmat yeah...
OTOH, this Parameter.perl is really Parameter.gist 13:50
if it's about roundtripping, we could as well do Parameter.new(flags => 723) etc
jnthn Well, .perl certainly needs to get it .perl'd
lizmat instead of figuring out how each flag influences how we look at it
jnthn Yeah, but .perl there is used when .perl-ing Block, Sub, etc. 13:51
And so you want a signature literal out of it really
So they can come out syntacticly sane 13:52

rudi_s Hi. I'm having a problem with the classify solution to split an array into two based on a predicate: my (@a, @b) := (1,2,3,4).classify({ $_ %% 2 }).{True, False} 14:41
It works fine if @a and @b are not empty, but if they are, it fails: 14:42
m: my (@a, @b) := (1,3).classify({ $_ %% 2 }).{True, False}

rudi_s RabidGravy: Thanks. But that's a little ugly. With just {True, False} it was nice, but this needs quite a lot of boilerplate. 15:01
RabidGravy I won my bet with mysefl 15:02
15:02 sufrostico left
rudi_s Which was? 15:02
RabidGravy there was going to be a "but"
rudi_s Well ;-)
Please don't tell me you think this is a nice solution for the simple task to split a list in two? 15:03
RabidGravy I don't have any opinion whatsoever about it
rudi_s Hm.
masak rudi_s: whenever you feel a solution is insufficiently nice or un-idiomatic, there's a particular language pattern that helps 15:04
it's called "named subroutines"
it can help abstract away some tedious code, pulling it out of the way of your main sentence 15:05
all the while providing an action or a transformation with a nice, domain-aligned designation
people underestimate this pattern
rudi_s masak: And how's that going to help? I have to write that small subroutine in each perl6 project where I need that particular feature. 15:06
masak yes, that's an excellent start, IMO
whenever the name makes sense, at least
timotimo C question, if i may 15:07
src/6model/reprs/P6opaque.c:686:52: error: lvalue required as left operand of assignment
(void *)(repr_data->attribute_offsets) += (char *)allocated_repr_blob;
geekosaur or you can make a private library of such things as modules
rudi_s I don't like duplication. Anyway, would be nice if perl6 had a short way to express that.
timotimo all i want to do is move the pointer on the lhs by the amount of bytes on the RHS. how do i spell that correctly?
masak rudi_s: one of the nice parts about this is re-use -- if you end up using the pattern in many places, and you need to change the underlying code, you only need to change the code in one place.
geekosaur timotimo, it's the cast that's doing it
LHS cast
timotimo geekosaur: right, but if i don't cast, wouldn't i have to divide the RHS by the pointer size of the LHS? 15:08
masak rudi_s: I guess it's all a question of what's more important at this point -- using an abstraction mechanism and making the code nicer, or being stubborn
rudi_s masak: Not sure if you're trolling.
masak not trolling.
genuinely trying to help.
rudi_s timotimo: You'd need to cast to char *.
timotimo i had (char *) on the lhs before, that errored the same way
rudi_s Pointer arithmetic is not defined on void *.
geekosaur casting to (char *) still makes an rvalue 15:09
rudi_s Yeah, what geekosaur said. void * vs. char * is a separate problem.
timotimo well, if i drop the cast, i get "invalid operands to binary +"
so i just won't be able to += ?
and instead replicate the LHS with the cast onto the RHS of a simple =?
geekosaur yep 15:10
rudi_s timotimo: Yeah.
But you don't need the cast on the left side (unless it's C++).
geekosaur note that old versions of gcc used to permit that because the optimizer removed the cast before it was detected 15:11
15:11 tadzik left
geekosaur so it seems to be biting a bunch of people who got used to gcc allowing it 15:11
timotimo OK
src/6model/reprs/P6opaque.c:688:79: error: invalid operands to binary + (have ‘char *’ and ‘char *’)
well, that's fun
rudi_s masak: I know I can abstract things, but I'd like to get core features in the language. 15:12
geekosaur hm
15:13 nakiro left
rudi_s timotimo: You can't add a char *, you can only add a int. 15:13
s/int/numeric value/
masak rudi_s: is this about wanting .classify to work differently? maybe the discussion would be more productive if it was clearer what exactly you're currently missing.
geekosaur timotimo, what is allocated_repo_blob? 15:14
(in particular what is its type?)
15:14 tadzik joined
rudi_s masak: I want to split an array/list into two based on a predicate. The first contains the ones where the predicate returns true, the second where it's false. 15:14
Btw. how can I return two arrays from a function so that I can do my (@a, @b) = foo()? 15:15
timotimo geekosaur: void *
masak rudi_s: the first list can be had through .grep
pyrimidine Anyone here interested in bioinformatics apps for Perl 6? Open Bioinformatics Foundation is accepting proposals for the Google Summer of Code: summerofcode.withgoogle.com/organi...329984000/
geekosaur so how were you expecting to add two addresses together?
did you want the size instead of the address? (you can't derive that from the address if it's allocated) 15:16
masak m: sub split_on_predicate(@l, &p) { [@l.grep(&p), @l.grep({ !&p($_) })] }; say split_on_predicate [1, 3], * %% 2
camelia rakudo-moar b9a79e: OUTPUT«[() (1 3)]␤»
timotimo geekosaur: the current value of those fields is an offset. so really, i'd want to reverse the arguments to +
masak rudi_s: about the same length as your solution, and much less cluttered ;) 15:17
geekosaur rudi_s, arrays, like other objects, are "passed by reference". so return (@a, @b) should work
not like perl 5 where it would flatten them into a single list
pyrimidine re: GSoC and OBF: not just limited to Perl 6 of course, but figured it's worth mentioning here :) 15:18
geekosaur timotimo, so they're not really pointers?
RabidGravy classify also has an (albeit undocumented) argument "into"
geekosaur (I know you're working on a memory manager, but if it's not actually a pointer then it's a bad idea to tell C that it is a pointer.)
timotimo geekosaur: not yet at that point

kalkin- ugexe: I've read your github comment on my PR for sergot/openssl. After reading the docs about Version, wouldn't it make more sense to use the build in Version type? Yes this will obviosly break the api, but it would be a saner solution, wouldn't it? 16:38
16:38 themonkeybob11 joined
ugexe kalkin-: than naming it something else like AllowedVersion? 16:39
kalkin- ugexe: it would be nice to have v2.0 v3.0 v1.2 in the when clause ;), but obviosly renaming is the simplest way 16:40
kalkin- is probably getting overexcited with the perl6 syntax sugar stuff
16:40 hankache left
ugexe if you take the where clause out of the signature you can then give a sensible error message as well instead of 'type constraint failure' 16:42
kalkin- ugexe: but then the compiler could not evaluate it at compile time, if i understand it right 16:44
16:51 sufrostico left, zakharyas left
ugexe maybe something like this as the first new candidate? `multi new(:$!version! where {Version.new($_) !~~ v1.1 | v1.2}) { die "this module only supports versions 1.1 and 1.2"; }` 16:52
you could use `Version :$!version! where * ~~ v1 | v2`, but that would break backwards compat with modules that use it 16:53
kalkin- ugexe: but the first example wouldn't be evaluated at compile time, or would it? 16:54
ugexe why do you want it evaluated at compile time instead of runtime? 16:55
kalkin- ugexe: because I want to catch errors early? It's not like there is a new TLS version every week, so it needs to be dynamically determined if a specific version is available. I prefer the compiler doing the work for me, or I would code in Python :) 16:58
But may be I don't full undestand the Prl 6 spirit 16:59
*fully understand*
sjn useful for static code checking/analysis? (e.g. automatically pick up requirements from code)
ugexe there are any number of ways to do that. but i dont think the signature is the place for it
sjn sees now that this was a signature 17:00
yeah, that's... hm.
API versioning might be nice, but perhaps a bit ambitious to put that information in signatures, yes 17:01
17:01 sufrostico joined
sjn wonders if API versioning can be done with roles 17:02
kalkin- why is it bad or ambitious? Like I said it's not like it needs to change that often and if TLSv1.3 will be released there should be no issue just extending the subset? Or am I missing something basic?
ugexe because 'failed type constraint' is not a useful error to the user 17:03

RabidGravy the Distribution is the thing that gets installed when some installer does "... install Foo" 17:14
kalkin- About the 'failed type constraint' error. A proper IDE would normally show that you are allowed only to enter the values 2, 3, .... May be the compiler could do the same? 17:17
RabidGravy: Ok but the Distribution api version is module specific, while the SSL version stuff are just different protocols, or did I misunderstand something? 17:18
ugexe but you can have `where $_ * 100 > 3 ?? die !! True`
17:19 themonkeybob11 left 17:20 Actualeyes left
ugexe because you could theoretically use :api to handle multiple versions of (most likely nativecall) apis/protocols/whatever in a single Distribution 17:20
sjn hm 17:21
kalkin- ugexe: you mean by adding some api suffix to my `use OpenSSL;` import?
sjn isn't :api about which API version a module *provides*? 17:22
ugexe yes, so it would probably provide a bunch of `new` methods to handle each type of version 17:23
you are providing the same apis in essence 17:24
kalkin- Ok but how would i map the following case (which currently isn't possible): I'm writing an application which I want to limit to support only TLS 1.1 and TLS 1.2. If the server does not support the both versions i want, i don't want to connect
(besides that using TLS does not work with the current api at all, i wanted to submit the bugerport for this, but first needed to fix the Int issue) 17:25
17:27 zpmorgan joined
kalkin- Or shouldn't the case of limiting to TLS 1.1 & 1.2 handled by the OpenSSL api at all, and be done in the application logic? 17:28
17:28 abraxxa left
RabidGravy yes, the latter, assuming you can get the version from the OpenSSL 17:28
the only way it would make sense in the libray API is if you can supply an optional matcher for the version when making the connection 17:30

kalkin- This is the issue i mentioned github.com/sergot/openssl/issues/22 For some reason OpenSSL always tries to use SSLv3 instead of TLS 17:34

ptolemarch Hi, there. I'm looking for information on Rakudo/JVM-Java interoperability. In particular, I can find a lot on calling Java from Perl6, but nothing on calling Perl6 from Java. 17:45
(I asked this yesterday afternoon, and I don't want to be a pest but I'm hoping to catch other eyes today...)
psch ptolemarch: github.com/rakudo/rakudo/blob/nom/...erver.java 17:46
ptolemarch: well, and the corresponding superclass, hang on...
ptolemarch: github.com/perl6/nqp/blob/master/s...erver.java 17:47
ptolemarch psch: Awesome. It looks like this accepts a String and can run the resulting code.
psch ptolemarch: in the end, to call into Perl 6 from Java you have to build the whole interpreter 17:48
where "build" means "set up"
ptolemarch psch: Sure, fair enough, especially 'cuz eval() and such.
psch: but is it possible also to run already-compiled code?
psch ptolemarch: there's an nqp branch that explored packaging into .jar, if that fits your use-case 17:49
ptolemarch: it's kinda stalled though, no tuits :)
github.com/perl6/nqp/tree/standalo.../tools/jvm
ptolemarch Interesting.
psch the .sh script there explains the process as used there, but it's quite an out of date branch
no idea how easy it'd be to get that merged into master, though 17:50
ptolemarch I'm able to get `perl6 --target=jar --output blah.jar blah` to work, at least in the sense that it creates a .jar, but I have no idea what code is really resulting.
17:51 kjs_ left
ptolemarch decompiling seems to result in a handful of `public static void` methods (none `main`), and classes embedded into the script don't seem to result in multiple .class files 17:51
psch ptolemarch: yeah, that gets you jvm bytecode that needs to be invoked via the Perl 6 interpreter
ptolemarch Huh. 17:52
psch well, not quite, actually
as in, the .jar contains program state after Perl 6 level BEGIN (or INIT, not sure) time 17:53
ptolemarch Here's what I'm hoping for: a jar, however big it needs to be, that I can use as a Minecraft server mod. :-)
oh, huh
that explains why there's both a [long hex hash].class and [long hex hash].serialized
psch and that still needs all the Perl 6 language level stuff to make sense to the JVM
ptolemarch Hmm.
I have no problem with the idea of a huge .jar with all the Perl6 interpreter in it. I'm just hoping to be able to write a mod in Perl6 rather than Java. 17:54
psch i don't know if the minecraft classloader can load nested jars, but if it can the standalone-jar branch should do most of what you need 17:55
well, assuming you can see through my minimal docs and get it working :S
ptolemarch :-) 17:56
psch if you don't need 6.c you can just get the nqp and rakudo standalone-jar branches as is and build them
ptolemarch Okay, this is somewhere to look, then. Thank you.
17:56 kjs_ joined
psch note though that you get lots of overhead and a very slow mod that way, 'cause you're effectively embedding a Perl 6 interpreter instead of adding a mod 17:56
ptolemarch Hmm. 17:57
I hadn't quite realized how very little of "compiling perl6 to JVM bytecode" was really going on. 17:58
psch well, our MOP alone doesn't fit directly onto the JVM 17:59
add &EVAL and things like BEGIN... vOv 18:00
i don't doubt that some jvm/indy wiz could make it all fit a lot closer, but those seems to be rather rare :) 18:01
ptolemarch Right. 18:02
Thank you for your help and advice. 18:03

psch gist.github.com/anonymous/0f7bdd4742cd745a1a37
that gist has the reason for why methods added with .^add_method to a Java class aren't found 20:37
apparently the JavaObjectWrapper STable has the authorative method cache
but the nqp::setmethcacheauth call in MethodContainer.add_method only turns off the meth cache authorativeness of the Perl 6 level STable... 20:38

psch i'd be tempted to fix this by adding a decont to the nqp::setmethcacheauth call in Metamodel::MethodContainer.add_method... 20:38

timotimo you're right, it looks a bit weird
DrForr Would I be incurring a significant runtime penalty by using 'my %routes{Any}'? I'm guessing it affects lookup at the very least.
timotimo you mean by making it an object hash? 21:45
DrForr Yeah.
buharin could you help me
my code works very slow
timotimo hmm, good question
buharin :/
timotimo buharin: please show us your code?
buharin sure
DrForr buharin: Put your code up on a gist or pastebin, we won't know until then. 21:46
timotimo that's right
also, you could give perl6 --profile foobar.p6 a try
see if that gives you anything obvious
DrForr timotimo: I'm rebuilding Prancer's handlers, and I want to be able to have stuff like undefined Str and Int as keys, so I can keep them out-of-band as handler types. 21:47
timotimo i believe object hashes will work with WHICH, could that be right? 21:48
it should be all-right performance-wise. but calculating a WHICH for strings and ints means to concatenate a bit of stuff, so there's that 21:49
