perl -e '"01234" =~ /^(.+)(.+)((?:.z?)+)$(?{ print "$1 $2 $3\n" })(*FAIL)/'
... program outputs only five variants and "0 1 234" disappears.

I see the same behavior on Strawberries 5.10.1.5, 5.12.3.0, 5.14.4.1 and ActiveState 5.8.9. (Have to use  (?!) in place of  (*FAIL) previous to 5.10, but these patterns are exactly equivalent.)

Why is this behavior seen? Dunno. Will have to think about this a bit.
