[pugs] array interpolation question

[Garrett Rooney]

It looks like the current pugs array interpolation doesn't quite match 
the description in S02.

S02 says that container references automatically dereference to the 
appropriate (white space separated) string values, which is fine, pugs 
does that now, but it also says that to interpolate an entire array you 
need to subscript with empty brackets, so if we've got an array @a = (1, 
2, 3) then "@a" eq '@a', but "@a[]" eq "1 2 3", at least from my reading 
of the synopsis.

So what's right, the spec or the implementation?
Assuming the spec is correct, here's a patch to add some more tests to 
t/op/string_interpolation.t.

Of course, those should have been todo_is tests...  Here's the right patch.

This a (hopefully friendly) note regarding cross posting between
perl6-compiler (p6c) and perl6-language (p6l).  We're still feeling our 
way around regarding "what belongs on p6c vs. p6l", but it seems
pretty clear to me that if the question is one of "perl6/pugs doesn't
properly implement feature X as given by the spec" then the post
belongs strictly on p6c.  We only bring p6l into the discussion if
the spec is ambiguous and it's something that can't be easily
decided/discussed within p6c itself.  This is just to keep 
cross-postings and traffic to a minimum.

Patches to pugs or the perl6 compiler certainly belong *only* on p6c.

This message isn't intended as a rebuke at all -- all of the patches,
questions, and suggestions are very welcome!  It's just a 
clarification since we're still just gettings underway on p6c.

Thanks, applied.
