Research direction

Start by locating the existing .remove_axis(), .insert_axis(), .into_subview(), and .slice_move() implementations and their dynamic-dimensional array types. Compare their ownership and dimension-changing behavior, then add and test &mut self variants whose results match the existing operations; review #425 for prior discussion.

Description

enhancement

The .remove_axis(), .insert_axis(), .into_subview(), and .slice_move() methods do not currently have in-place variants that change the number of dimensions, because for fixed-dimensionality arrays the type changes when changing the number of dimensions. However, dynamic-dimensional arrays do not have this limitation. It would be useful to have variants of these methods for dynamic-dimensional arrays that take &mut self instead of self as the argument.

See #425 for some discussion.
