colomon ???
colomon still have no clue why the bug
masak so you agree it's a bug?
colomon seems like it's got to be, one way or the other.
* masak submits rakudobug
colomon I mean, either going through the loop the first time is
wrong, or not going through it the second time is.
colomon unless there's something really subtle and disturbing going
on.
Now it (properly, I think), dies on the first iteration:
17:05 [Coke] rakudo: for ^8 { .=fmt(%03b); .say }

[perl #78738] [BUG] Multiple dispatch on required named param makes 0-parm sub invisible
On Sun Oct 31 16:38:58 2010, util wrote:
On Rakudo Star 2010-10, this code works as expected, outputting 42\n
:
multi sub Bar ( ) { return 42 };
say Bar();
This code should give the same output (and *does* on Pugs):
multi sub Bar ( ) { return 42 };
multi sub Bar (:$baz!) { return $baz };
say Bar();
Instead, Rakudo dies on this error:
No applicable candidates found to dispatch to for 'Bar'. Available
candidates are:
:()
:(Any :baz($baz)!)
Fixed:
17:07 [Coke] rakudo: multi sub Bar ( ) { return 42 }; multi sub Bar
(:$baz!)
{ return $baz }; say Bar();
17:07 +p6eval rakudo 33f1cf: OUTPUT«42»

IMHO, required named parameters should default to being part of the
longname.
In any case, the current behavior looks like a bug.

Util In Rakudo, why is the second declaration interfering?
masak looks like a bug to me.
masak ...possibly reported already.
sorear Perl 6.0 is not required to support multiple dispatch
with named parameters
masak but I thought Rakudo did.
jnthn No
jnthn Well, it doesn't consider them other than as constraints.
jnthn e.g. if one is required it's a constraint.
Util sorear: it is more than just a named parm; it is a
*required* named parm.
Shouldn't that make it part of the dispatch?
masak apparently, it's difficult to do that in practice.
jnthn Rakudo already considered required named params as
constraints.
jnthn Otherwise a bunch of our trait_mods would never work.
jnthn It even has an optimization for the
single-required-named-param case. :-)
jnthn Util: Can you file a ticket?
jnthn That looks like a bug to me. :S
Util Will file rakudobug. Thanks, all!
jnthn Util++
jnthn But it turns out to be a silly thinko. :-)
jnthn Somewhere in that little file, perl6multisub.pmc :-)
jnthn masak: There's another one in RT that I think is distinct
from this but may end up related in the end.
masak jnthn: ok. I didn't find anything about required nameds.
jnthn masak: I think it was about an argless candidate.
jnthn Or at least, that's the common dominator between these
two.
