[issue35431] Add a function for computing binomial coefficients to the math module

[Raymond Hettinger]

Raymond Hettinger <raymond.hettinger at gmail.com> added the comment:

I don't have a preference one way or the other (both ways have plausible arguments, error checking vs utility beyond simple combinatorics, and both ways have ample precedents).

That said, if we're going to ultimately relax the constraints, it would be better to do it now before the API is released.  

Even if we were already in feature freeze, it would be okay to change it (the purpose of a beta is to elicit end-user feedback which is what David has just given).
