Since an array has the factorial of its element count possible orders, your $input must have that range to obtain a 1-1 relation. Are you sure that so stringent a requirement is needed?

Check out List::Util::shuffle(). It may be good enough for what you want.

You won't want to keep C++ comments in your perl, and prototypes are usually not desirable. See perltrap.
