[perl #121994] Array receives an empty itemized list

[Christian Bartolomaeus via RT]

This also works now on Moar:

$ perl6-m -e 'my @a; @a.push: $("one,two,three".split(",")); say @a;'
one two three

There was a test added to S02-types/lazy-lists.t with the following commit: 
https://github.com/perl6/roast/commit/6538a38cfe5492fc65412440e56a46c3163fb6f9

I just fudged the test for JVM.
