NumPy is so tied to the C API that it's very hard to avoid. We in Python, we re-implemented most of NumPy, but we are still missing out on the entire ecosystem. So our answer to that is CFFI, which is a very, very simple way to go see from Python. See, and CFFI took off like crazy. It gets over a million downloads a month, which is quite crazy. Like, for most things like database drivers, there's a CFFI-ready replacement that works as well and usually a lot better on PyPy.
