Numpy is a dedicated library where the critical code is in C, but that's a library, hardly a language feature. I don't know if there is any numerical processing library in Ruby.

Cython is not intrinsic to Python either. I see there is a ruby2c gem, but I have no idea how it compares to Cython.

As for pypy, that's about switching to a different runtime, the same way Ruby people would go to JRuby.

None of this turns Ruby into apples and Python into oranges, I'm afraid.
