A possible future usage of user-defined slicing

[bearophile]

This is an useless post. Sometimes it's good to look at code in 
other languages, and see their idioms, or to have an idea where 
to go.

This is a simple problem, it just asks to simulate some rotations 
of a Rubik's Cube:

This is a correct Python solution:

I presume that with Kenji patch 
(https://github.com/D-Programming-Language/dmd/pull/443 ) we can 
define multiple $ and slices in user-defined code, to implement a 
good Matrix, D code like this could be used:
