N-D arrays in D2

[dsimcha]

Does anyone know of a decent library for N-dimensional arrays that supports D2
and is reasonably well-tested and easy to install?  I'd prefer if it supported
matrix operations, just so I could familiarize myself with these for when I
need them, but my immediate needs are just N-D arrays.  I could just use
something like real[][][], but I'd prefer something more efficient and
syntactically prettier.
