Yep. I can imagine that that's avaiable as:

I've started tweaking internals to get a faster calling scheme in place.
Part 1 (in CVS) moved the subroutine's address into the parrot_sub_t
structure. Accessing such Sub-internals via get_pointer set_pointer is
working still safely.
Anyway, next will be to hide the return continuation in

That's fine too.
