Good point. We should probably prefix all perl 6's data types and functions 
like we do in perl 5. Perl_ for functionish things, PL_ for dataish things.

Well, we've got an unsigned version of the native type, but I don't see 
much point in one for the bigint--one bit in a fixed 32 (or 16, or 64) 
makes a difference, but one bit in some variable-length integer doesn't 
seem to be really worth the extra trouble.
