Research direction

Start by reading the existing multislice! macro and the slice_axis API to understand their syntax and behavior. Add multislice_axis! with the call shape shown in the issue, then add coverage demonstrating multiple mutable and immutable disjoint slices along an arbitrary axis.

Written by the indexing model from the issue text.

Description

enhancement

The next release of ndarray will have a multislice! macro for easily taking multiple mutable, disjoint slices simultaneously. (#388) This is great, but there are cases where you want to slice only a single axis given that axis number (analogous to slice_axis versus slice) for an array with an arbitrary dimension type. It would be useful to provide a multislice_axis! macro that can be called like this:

let (a, b, c, d, e) = multislice_axis!(arr, Axis(2), 0..5, mut 6..;2, 1..6, mut 7..;2, 3);
