[gazing into crystal ball . . . ] I predict some header somewhere is going
to already #define "INT".  Perhaps PERL_INT and PERL_NUM ?

Do you also want an unsigned variant?  (trying to spare Nick some of 
the sign preservation madness he's currently battling in perl5.)

So presumably PERL_INT could be "long long" but IV might just be "long".
Hmm.  So how do you carry around a PERL_INT inside the perl6 source?
