Something so that:

>>> the_func([1, 2])
array([1, 2])
>>> type(_)
np.ndarray
>>> the_func(1)
1
>>> type(_)
np.int32

Can be implemented trivially as

def the_func(x):
    return asanyarray(x)[()]

What should this be called?

  • asanyarray(x, ..., allow_scalar=True)
  • asanyarrayorscalar(x)

On the C-api side there is a function, something like PyArray_ReturnArray or so, which does this conversion. The indexing is just a hack that comes close to doing the same thing really.

@eric-wieser I’m going to close this issue as the proposed feature didn’t get support from the NumPy dev team at 2023-02-08 meeting where it was reviewed.
