Actually I think it'd be fine to take int8.  We'd not be able to cope
with any larger input anyway, and the inner loop could be noticeably
faster if the control logic just deals with int.

We could leave the factorial(numeric) case open for a future
implementation that uses gamma, if anyone gets hot to do it.
