Research direction

Start at the ArrayView::from_shape entry point and trace how shape and strides are validated for view construction. Determine the intended handling of stride-zero axes with length greater than one, then verify that such broadcast-like views are accepted without breaking existing aliasing behavior.

Written by the indexing model from the issue text.

Description

enhancement

It is safe for ArrayView instances to have aliasing elements. It would be good to add support for this in ArrayView::from_shape. I'm not sure whether we should support all possible types of aliasing, but it would be good to at least add support for stride 0 for axes with length greater than 1. (Views like this are often the result of broadcasting.)
