Re: [Numpy-discussion] New DTypes: Are scalars a central concept in NumPy or not?

I have some thoughts on scalars from playing with ndarray ducktypes (__array_function__), eg a MaskedArray ndarray-ducktype, for which I wanted an associated "MaskedScalar" type. In summary, the ways scalars currently work makes ducktyping (duck-scalars) difficult: * numpy scalar types are not

[Numpy-discussion] Suggestion: prevent silent downcast in np.full_like

Hello, This is my first activity on this mailing list, please let me know if I am doing anything improperly. I recently opened issue #15635 and it was suggested to me that it could be worth discussing here. Here is a summarized code example of how
