your program does a lot of permutations and combinations) I somehow suspect
factorial doesn't actually get called so often that it needs to be in stdlib
or core. Its also not one of those math functions where you have to "know
the trick" (not that its a terribly complicated trick) to implement it like
Math::exp. I can't think of a good use case. although maybe its just me.
