That's certainly the best way, and that's why I am a bit wary about 
replacing python code by cython (once it becomes possible to 
compile/accelerate pure python code, we would have to code cython 
modules again; I would much prefer replacing some C by cython, and be 
sure there is always a pure python implementation available, even if 
really slow).

Not that it is in any useful form, but pypy folks are now working on 
supporting floating point operations in their jit:
