| - An `IndexError` exception must be raised if the number of provided single-axis indexing expressions is greater than `N`. | ||
| - Except in the case of providing an ellipsis to index all trailing dimensions (e.g., `A[2:10, ...]`), the number of provided single-axis indexing expressions must equal `N`. For example, if `A` has rank `2`, a single-axis indexing expression must be explicitly provided for both axes (e.g., `A[2:10, :]`). An `IndexError` exception must be raised if the number of provided single-axis indexing expressions is less than `N`. |
There was a problem hiding this comment.
Just noticed the word "trailing" should not be here. An ellipsis can go anywhere in the index, not just at the end.

Also shouldn't this be "should" instead of "must"? Do we want to require this restriction or just limit what the spec requires?
