Awesome, good job! I am sorry I don't have much time to help with that, but when you make some progress with the assumptions, I'll help to port that to SymPy, because this is really needed. > > I don't think that is reasonable to start writing sympy in C/C++ > (btw, I also would prefer C over C++), > we still have many issues unsolved even in Python. > However, I think writing Rational/Fraction classes and related > routins in C/C++ might give considerable speedup and it would > be useful already.

I think the Rational/Fraction classes should be done in Cython, or at least wrapped using Cython - the wrappers are virtually the same good as if you did that by hand, but freaking easy to write/maintain.
