Description
The mapping for layout_stride has a strides() member function to retrieve at once all the strides whereas layout_left and layout_right do not. I was wondering if it could be possible to require for all mappings satisfying is_always_strided() to implement both stride(size_t) and strides() ? This could ease writing generic code with a strided_layout concept.

Research direction
Review the proposed layout_stride, layout_left, and layout_right mapping interfaces and the is_always_strided() requirement described in the issue. Determine whether requiring both stride(size_t) and strides() is appropriate for a generic strided_layout concept; done means the proposal has a settled direction and the interface requirements are clearly documented.
