A short time ago, something similar came up.

I think the built-in's should stay simple, and a module (or several 
different ones) can exist to do comprehensive features for 
multi-dimensional arrays.  Designing that is really a separate project 
in itself, and it may shake out with use.

So keep it out of the core spec.
