I havent quite decided what the merits are of relegating perl5 stuff to a perl5 binary, but a
preliminary judgement of the idea is that I like it a lot.
Yea, but did you see this from Ed Peschko (and related comments) in this
thread:
    If perl6 is designed correctly, then it should be *extremely easy* to target
    multiple, differing syntaxes. TMTOWTDI on a grand scale..
    And what would be a better way of testing this out than being able to
    make perl6 parse and run perl5 code correctly?
