[Numpy-discussion] removing NUMPY_EXPERIMENTAL_ARRAY_FUNCTION env var

[Ralf Gommers]

Hi all,

In https://github.com/numpy/numpy/pull/23364 we touched on the
NUMPY_EXPERIMENTAL_ARRAY_FUNCTION environment variable. This was a
temporary feature during the introduction of `__array_function__` (see NEP
18), but we never removed it. I propose we do so now, since it is
cumbersome to have around (see gh-23364 for one reason why). GitHub code
search shows some usages, but that's mostly old code to explicitly enable
it or print diagnostic info it looks like - none of it seemed relevant.

In case there is any need for this functionality to disable
`__array_function__`, then please speak up. In that case it probably
applies to `__array_ufunc__` as well, and there should be a better way to
do this than an undocumented environment variable with "experimental" in
the name.

Cheers,
Ralf

+1 for removing this environment variable. It was never intended to stick
around this long.
