Dispatching on `where=` in `__array_ufunc__`?
Hi all, Without concerns voiced, I will probbaly merge the PR: https://github.com/numpy/numpy/pull/23240 soon. It proposes to dispatch also on the `where=` argument to ufuncs for __array_ufunc__. This allows a use-case of an "uncertainty" boolean array (which is not really boolean). I guess there may be other use-cases, although I am not sure. It thus may be a bit narrow in scope. The main effect of this should be that implementors of __array_ufunc__ may have to add logic to check for `where` in the kwargs (eventually), otherwise a user passing their array type as `where=` might run into issues (for some types). That is slightly tedious, but I doubt it causes much issues in practice (where isn't used much, and for most types it doesn't matter much either way, except for rejecting weirder inputs). Cheers, Sebastian
