japhb Is there a shorter or more idiomatic way to exhaust a finite generator than 'my @a = gather { take $_ while ($_ = gen-func()).defined };' ? 00:07
I'm afraid I've got brainlock at the moment
flussence 1 while gen-func().defined; might work, there's probably a better way of saying it though 00:10
japhb ... I should have specified: I actually want the values obtained during the exhaustion. :-) 00:11
sorear japhb: take (gen-func() // last) while 1; maybe 00:12
flussence oh whoops, ignore that then :)
00:12 molaf_ left
japhb sorear, hmmm, interesting 00:13
At least it avoids the $_ blech
sorear there's also while gen-func -> $x { take $x }
which is not quite the same 00:14
japhb Yeah, I really need to gracefully handle gen-func producing false-but-defined 00:15

sorear colomon: FWIW, I'm not entirely sold on open returning IO 01:52
colomon me neither 01:53
sorear colomon: "/path".IO is used to produce magic pathname objects for filetests; by S13(?), .IO ought to return an IO object
and I really think that pathnames and file handles are not the same thing
even if there is the old stat/fstat dualism 01:54

ah, at the rnull, I bet. 03:02
colomon yeah, the code there looks okay as far as I can tell. but you can't call it with an rnull, if that's what you're doing 03:05

colomon ?
oh, I see the question 03:29
I believe the correct answer is "not yet"
ruoso in the sense that it somewhat does? or in the sense that it's in the plan? 03:30
colomon I'm pretty sure it doesn't have anything like it now, but sorear's been studying it carefully
ruoso oh... ok...
I am considering prototyping some of the threading things... 03:31
(in special the blocking-buffered-stream thingy)
and maybe niecza might be easier to do that prototyping than rakudo... considering VM support for threads 03:32
colomon sounds reasonable to me. 03:33
[Coke] colomon: I'm going to do another test summary run. should I wait?
ruoso is there some documentation of the internals of how niecza is implemented? (runtime-wise)?
colomon [Coke]: yeah, give me a minute
ruoso: maybe github.com/sorear/niecza/blob/mast...mpiler.pod 03:34

The blocking aspect should work both ways, not only the reader should block on the writer but it is also important that the writer blocks on the reader so that we only advance a reasonable set of data prior to any consumption. Just like unix pipes.

since they are *private*, the user shouldn't automatically be allowed to provide a value for them 07:20

moritz are sure you don't want them public?
diggins yes
they are implementation specific
instead of using BUILD, can i use new? 07:21
moritz you can
diggins: but if you want to allow setting them in .new, they look like part of the API
diggins when i tried, i got the error listed in my paste
moritz well, depends on how you made your new 07:22
diggins similar to BUILD
moritz you need to call self.bless in method new to create a new instance

kshannon comparing the code generated for the two loops above, there's quite a bit of difference. I think it's definitely more than one boxed int difference. 12:09
My calculations are boxing an int takes about 80 bytes. 12:11
moritz well, I'd expect the native ints to inline the infix:<+> call
kshannon Yeah, but then it gets boxed any for no apparent reason and thrown away... :( 12:13

masak I don't think the spec mentions anything like that.
geekosaur wonders: is that an overzealous type checker, or something believing that infix:<+> should be commutative and that the where clauses mean it needs to declare the commutative version --- because its not catching that they are the same
moritz well, the multi dispatcher needs to do a topologic sort
geekosaur (that is, autogenerate ($b, $a) given ($a, $b)
masak it's from src/binder/multidispatch.c 14:11
moritz and that sort does a narrowness comparison
and if it detects a cycle, then it gives that error
14:11 shinobicl__ left, mkramer joined

masak but I can't say I see what the circularity would be. 14:12
moritz things is, if that candidate generates a cycle, there needs to be one candidate that's more specific than the new one

14:12 ggoebel joined
moritz hm, maybe it treats str an epsilon tighter than Str? 14:12

maybe it's a bug in the candidate sorter, or in the narrowness analysis

actually, the question I went in to try to answer was "does S06 think that macro-inserted code always have a Block around it?" 19:25
sorear once said that was his interpretation of it.
and indeed, S06 talks a lot about hygiene and stuff, all of which would be facilitated by having a block around everything... except for the part about being able to un-hygienically declare variables. 19:26

colomon sorear: will that work for the constant values? 20:57
sorear yes, if you can get the ordering right
$_enums needs to be set up before the constants are declared
which probably means that Order needs to be moved after EnumMap
which might require a package stub at the top, and/or using ::Order::Increase syntax 20:58

colomon [Coke]: looking at .fmt now
[Coke] I assume this is all cool from a licensing/copyright perspective, yes?
sorear yes, rakudo and niecza both use the Artistic-2.0 license 22:40
I think "git blame" is good enough for tracking attributions, mention Rakudo in the commit message 22:41
[Coke] \o/
Aye.

geekosaur imagines .fmt functions in diapers running around the place 23:08
