Ditto. As I said yesterday, my current preferred option is that a list ref
of list refs will also support a multidimensional indexing syntax.
Furthermore, if it has a single basic data type and is declared ':compact'
it should be stored in a contiguous block of memory. Finally, I believe that
we need to adjust RFCs for reduce(), list generation, and
zip/unzip/partition/reshape to work with n-dim matrices.

Oh, and we also would need to look at how we can hide as much of the
dereferencing as possible.
