Array API 2024 tracking issue

[tomwhite]

Note that the Python array API standard v2024 is still in draft.

The following is based on closed issues, and will be updated once the 2024 standard is released.

New array functions

elemwise

These should be straightforward to add.

• [ ] nextafter
• [ ] reciprocal

indexing

• [ ] take_along_axis

searching

• [ ] count_nonzero

statistical

• [ ] cumulative_prod

utility

• [ ] diff

Updates

• [ ] Add max dimensions to capabilities
• [ ] Add support for complex input to mean
• [ ] Add support for scalars in result_type
  • We delegate result_type to the backend array library so this shouldn't need any changes.
• [x] Add scalar support to where
