Ok, this is basically a repost of a part of Re^3: [Perl 6] Object methods on the fly?, in which I probably asked too many further side questions, all of which OT wrt the main thread. So I'm asking again here in the hope that it will have more visibility...

I tried the following in pugs:

pugs> my @array does role {
....>     multi method insert ($x) { @.push($x) if none(self) eqv $x }
....>     multi method insert (@x) { @.insert($_) for @x }
....> } = 1..5;
(1, 2, 3, 4, 5)
pugs> @array.insert($_) for 2..6;
pugs> say @array
123456
Bool::True
pugs> @array.insert(3..7);
pugs> say @array
12345634567
Bool::True

I would have expected the second say() to similarly print 1234567. (If I use *@x, pugs "hangs", instead.) Did I miss something or is perhaps this only a specific implementation, namely pugs, problem?

Update: TimToady answered in the context of the original thread:

Finally, I think the failure of the multi form is just hitting some things that aren't completely implemented in pugs yet.
