<masak> rakudo: multi sub foo(Int $n where 1) { say "OH HAI" }; sub
foo(Int $n) { say "CHEEZBURGER" }; foo(1)
<p6eval> rakudo ec69e2: OUTPUT«CHEEZBURGER␤»
<masak> anyone know if that's in RT already?
<jnthn> That should be an error unless there is a proto in scope.
<masak> right.
<jnthn> (which in this case there wasn't)
<jnthn> rakudo: proto foo() { }; sub foo(Int $x) { 1 }; sub foo(Str
$x) { 2 }; say foo(1); say foo("a");
<p6eval> rakudo ec69e2: OUTPUT«1␤2␤»
<jnthn> Anyway, it works.
<masak> jnthn: aye, but the CHEEZBURGER one shouldn't work.
<jnthn> aye, we should complain loudly about that one.
