Status changed from Open to Feedback

I have two questions:

- Do you have some concrete use cases in which this new feature is used?
- Why don't you make a gem library to provide this feature?  or  Are there gem libraries providing it?

Feature #11003: Fast modular exponentiation

I would like to suggest, implementing "fast Modular Exponentiation " (http://en.wikipedia.org/wiki/Modular_exponentiation) for fixnum class.
Eg: A function like pow(a, n, MOD) can be computed more efficiently than (a**n) % MOD
