If we are adding this specific check, should we maybe also add a
hasattr(val, "__array__")
for also including "numpy-array-likes"?(although that can maybe also decided in a separate JIRA)
It's just that the current set of types we try to convert to an array is somewhat arbitrary. List and np.ndarray are of course the logical things to support. But the current check would mean that, for example, a pd.Series or a generic sequence are not accepted (while
asarray
will accept those)There was a problem hiding this comment.

Agreed. I opened ARROW-15202 separately because
pa.array
also doesn't check for__array__
. So not supporting__arrow_array__
here seemed like a bug to me, whereas supporting__array__
in general seemed more like a feature request.
