Internal mainly. There'll be prototype and attribute changes at the perl
level, but they're pretty trivial. (What they'll be is up in the air, but
there'll have to be some) Perl subs get passed in a list of variable size,
while opcode functions will get passed in a known number of parameters,
likely in registers. Or on the stack, depending on the platform.
