Description

Hi - what happens when the any of indices passed to __getitem__ are integers, or list of integers? E.g.

>>> a[:, 3] 
>>> a[:, [3, 4]]
>>> a[[1, 2], [3, 4]]

Does the active reduction work in these cases?

Research direction

Start by locating the Python implementation of getitem and any tests covering integer or list-based indices. Check how the existing active reduction behaves for the three examples, then define and test the expected behavior for scalar, list, and paired integer indices.
