Or, in fact, do the reverse: Implement the base class in Cython and inherit from it in a Python class that extends it. That would give you a fast, native extension type at the base and leaves you with all the freedom to extend it in Python code or even natively in other Cython code. I strongly recommend not to resort to writing real C code here (using the C-API of CPython). It will be slower and will contain more bugs.
