camelia True
jnthn Huh, what does a block like that with a trailing if even mean?
13:40 brrt joined
AlexDaniel `{ foo } if $x` is same as `foo if $x` 13:40
except that you can put multiple expressions in there
I do use that in my code, fwiw
SqrtNegInf Done
jnthn Wow...I highly suspect that is an accidental feature.
13:41 p6bannerbot sets mode: +v brrt
jnthn And, apparently, not part of spec 13:41

greppable6 AlexDaniel, 114 lines, 51 modules: gist.github.com/df00148dc77f7da44b...86ecc8b0b5
AlexDaniel jnthn: it could be part of spec, just without using the $_
jnthn Hm, possibly 13:42
AlexDaniel mentioned in the docs too: github.com/perl6/doc/blob/74189ce5....pod6#L159
and that's me using it :) github.com/perl6/whateverable/blob...le.p6#L108 13:43
jnthn I guess it kinda makes sense.
AlexDaniel I guess in many cases it makes sense to flip it around, not sure why I wrote it that way there
jnthn Yeah, even knowing it's legal, I'm doubtful I'd use it
Of course, will look into it, at least once I'm done with my current mystery :) 13:44
Geth rakudo: AlexDaniel assigned to jnthn Issue Scope flattening causes inner scope to lose value of topic variable github.com/rakudo/rakudo/issues/2601
7aa796a90e | (Daniel Green)++ | src/vm/moar/spesh-plugins.nqp

The guard set doesn't end up matching the values being passed, so the plugin is repeatedly called when it shouldn't be.
AlexDaniel SqrtNegInf: I'm curious, how did you find it? 13:45
SqrtNegInf I do daily smoke-testing on Perl 6 tasks from Rosetta-Code. Though this particular item was not part of the task itself, but my own testing procedure. 13:47
AlexDaniel interesting 13:48
SqrtNegInf TBH, though I thought the problem worth mentioning here, I replaced that particular construction. 13:49

lizmat m: dd ::("Int:D") # shouldn't that just work ? 16:11
camelia Failure.new(exception => X::NoSuchSymbol.new(symbol => "Int:D"), backtrace => Backtrace.new)
jnthn Don't think so 16:13
There's no symbol of that name
By that argument ::("Array[Int]") also should, among other things 16:14
Um, if we argued that Int:D should work, I mean.
lizmat ok, so given a string "Int", can one create the type Int:D ?
or is there no such thing ? 16:15
jnthn First resolve the string into the Int type object, and then something like Metamodel::DefiniteHOW.new_type(:base_type(::('Int')), :definite) 16:17
Well, I put the resolution of the string in there
lizmat ok, gotcha 16:23
couldn't we make a Mu.method out of that ?
jnthn No, I think MOP is appropriate here 16:26
Adding an extra method to every single object that exists is a bit much when this is the first time it's been asked for 16:27
lizmat ok 16:30

Geth rakudo: 7dea20aba1 | (Elizabeth Mattijsen)++ | src/core/Parameter.pm6
Parameter.$!nominal_type is always bound

So no need for decont()ing. Also add some comments to make sense of the bitmap values.		 17:53
17:57 [TuxCM] left
Geth rakudo: df8c578066 | (Elizabeth Mattijsen)++ | src/core/Parameter.pm6
Use clearer bit shifting instructions

Because they are constant folded anyway.		 18:17
timotimo oh, they are? cool! 18:43
oh, it's a "my constant" so it's compile-time evaluated
regardless of any constant folding the optimizer might do 18:44
lizmat if you just use it in "my $a = 1 +< 24", it's *also* constant folded 18:46
timotimo that's good, too

First stab at making Parameter a first class citizen

You can now call Parameter.new with the following named parameters:
   name the name of the variable (including any sigil, twigil and
   postfix of optional "?" or mandatory "!" and any ":" prefix
   to indicate a named parameter.
