I have started implementing NEP-18 in a pull request:

I propose a multi-step process for implementation:
1. Write a correctly working version of the core __array_function__
machinery in pure Python, adapted from the example implementation in the
2. Rewrite bottlenecks in C.
3. Implement overrides for various NumPy functions.

I think the first step is mostly complete, but I'm particularly looking for
help with the second and third steps, which should be able to happen
incrementally and in parallel.
