Couple other curiouse things to me which is around nowing the actual granularity of these values I think narrow rather than Num me be more appropriate but doing that also seems inconsistent when comparing the Instant values with Durations results. 05:44

daxim no, I mean a `grammar Foo {}` grammar

camelia 2
moritz these are two cases where .list is interesting
daxim can we look at the real output? 08:35
I think the list method call coerces something
m: grammar Foo { token TOP { <alpha>+ }; }.parse('a').perl.say 08:36
camelia Match.new(orig => "a", pos => 1, hash => Map.new((:alpha([Match.new(orig => "a", pos => 1, hash => Map.new(()), list => (), from => 0, made => Any)]))), made => Any, list => (), from => 0)
moritz sure, you can say() the match objects, I just recommend doing it at a real terminal
daxim empty list
08:36 XieST joined
daxim ok, once again, with the grammar Foo {} construct, is the list attr ever filled in? 08:36
moritz yes, becaues TOP itself wasn't quantified
alpha is quantified, so $/<alpha>.list makes sense 08:37
08:37 p6bannerbot sets mode: +v XieST
moritz the other thing that fills Match.list is positional captures 08:37
m: say (grammar { token TOP { (.).(.) } }).parse('abc').perl 08:38

masak if we're generating bytecode from a language with macros, do we even need to put the macro bodies in the generated bytecode? 09:53
I mean, it's not like we're going to call those macros at runtime 09:54
(S06 has some wording about `moo()` being a "compile-time call" and `&moo()` being a "runtime call" to the macro. but I don't think that holds up to closer scrutiny. I can elaborate further if someone wants.) 09:55
(or, let's put it like this. my current stance "I don't think that works" really means "I'm unable to imagine how that would work". it's perhaps more a limiation in me than anything else.) :) 09:59
anyway, given that we're *not* calling macros at runtime, it seems to me we should at most be installing a callable stub which complains when called. 10:00

moritz a bug in rakudo 23:47
jnthn When signature binding fails, the slow-path binder is used to figure out what went wrong and report a good error. That error occurs when instead it is perfectly happy with the binding, so fails to produce the error. This should never happen (and I've not seen it do so for a long time, so congrats or something...) 23:51
vrurg Aha, I guessed it's a bug (the text suggests) but can't strip it down to simple code. 23:52

vrurg Perhaps would have to link to github in my report. Again. 23:53
