I agree with this type of use case (whatever the syntax is). But I think there are too many small issues around it currently to do that in NumPy. For that the new DTypes need to move along a bit further, so that we do not lock-in nice syntax with features that have lots of quirks. See also: https://numpy.org/neps/nep-0041-improved-dtype-support.html https://numpy.org/neps/nep-0042-new-dtypes.html I think you could do much of such syntax now, but I would suggest to do it outside of NumPy proper (at least the experimentation) at this time for that reason. Hopefully, it won't be too long until we can think of creating such API for good inside NumPy.
