The fact that other languages have factorial does not in itself impress me. What is the actual use case other than illustrating computational induction (whether by iteration or recursion) and for calculating binomial coefficients? I don't really like the idea of making factorial a method for the same reason that exp, sin, ....... are not methods of float: there is no end. People should be able to learn basic classes without specialized functions attached.
