Hello,
I found a way how to correctly implement multidimensional
functional map for ndslices and for packed ndslices (tensors
composed of tensors). It allows
1. a compiler to use vectorisation with SIMD instructions like
`fabs` or `sqrt` for example. But first [1] should be merged
2. to manage mapped ndslices as common ndslices.
In additional the future ndmap abstraction has zero computational
cost.
The are 6 ndslice PRs, which should be merged first [1]. Please
help to review and merge this. They does not contain any new API
names, but optimizations and small API enhancements, which was
delayed before because I wanted to get enough experience with
ndslice first.
ndslice is in experimental and it is the most generic package in
Phobos along with new regex. Regex has a lot CTFE-able magic,
ndslice operates with abstract entities. Feel free to ask
questions if you want to have more detailed imagination about
implementation.

Thank you and best regards,
