I like cython, but I think it pigeon-holes developers: i've seen hardware modules written in Cython, when they could easily switch to C++ and provide a library that could be used as an FFI in any language, but instead locked themselves (and users) into the narrow world of Python. Is there a way to convert a Cython module(s) to C++, or at least a .o file? They are so dang close.
