Too late, because we now have a math.factorial() function.

As for numbits, I think it should be a method, because while it's very fast for the current implementation of longs, it could be longer to calculate for a long implementation using something other than a power-of-2 base.

Having it as a method may also be more consistent with a hypothetical popcount() method.

Antoine.
