In Perl you can never return an Array or Hash directly, only a reference to
such (unless you get into list coercion, but that's clearly not what you
want here). This goes for Perl or Perl XS. You can only return scalar values
(strings, integers, references, etc) from routines.
My XS is rusty, so I'll refrain from posting psuedo-code lest I confuse you.
Hopefully you get the idea.
I'm too tired/lazy to attempt a stab at your second question. Sorry ;)
