Perl5 just used a string as the generic c-struct handle as far as I know..
Then you use pack/unpack to access it further (assuming the programmer knew
what they were doing). There are tiny gotcha's (such as we'd have to have
flags so the GC knew the data wasn't in relocatable memory, etc), but since
we need that sort of support for perl5, I don't see a great advantage is
creating a new datatype for perl6; unless our least-common denominator needs
it I guess (e.g. lisp, python, etc).
