[Numpy-discussion] How to Capitalize numpy?

My answer to that: "NumPy". Reference: logo at the top of
https://numpy.org/neps/index.html .
In NEP-30 [1], I've used "NumPy" everywhere, except for references to
code, repos, etc., where "numpy" is used. I see there's one occurrence
of "Numpy", which was definitely a typo and I had not noticed it until
now, but I will address this on a future update, thanks for pointing
that out.

If you want this to be widely used, that will need an answer or at least some rough guidance though. For example, we would expect a duck array to have a mean() method, but probably not a ptp() method. A library author who wants to use np.duckarray() needs to know, because she can't test with all existing and future duck array implementations.

It seems pretty clear to me that it's mostly aimed at library authors rather than end users. And also that mature libraries like SciPy may not immediately adopt it, because it's too fuzzy - so it's new libraries first, mature libraries after the dust has settled a bit (I think).

In the NEP/docs, at least saying something along the lines of "if you implement this, we recommend the following strategy: check if a function is present in Dask, CuPy and Sparse. If so, it's reasonable to expect any duck array to work here. If not, we suggest you indicate in your docstring what kinds of duck arrays are accepted, or what properties they need to have". That's a spec by implementation, which is less than ideal but better than saying nothing.

>> >>> 2. The protocol should use *something* more clearly namespaced as NumPy specific than __duckarray__. All the other special protocols NumPy defines start with "__array_". That suggests either __array_duckarray__ (sounds a little redundant) or __numpy_duckarray__ (which I like the look of, but is a different from the existing protocols).
