Does that mean that opcodes like these are just going to call functions
pointed to by vtable entries (that is, not have a 'default

It makes more sense to me to just have these functions act on numbers
(like float and bigfloat), and auto-numify like Perl 5 does. Forgive me
if I am missing something (I usually am :).
