The high-level-stack-language is so beautiful, and Factor is the only one
around afaik.
Given a large enough vocabulary, Factor would outshine Python, Numpy,
Matlab, Mathematica, etc.

I started an n-dimensional array implementation in extra/arrays/shaped.
Check out this paper on numpy's nd-array: http://arxiv.org/pdf/1102.1523.pdf
The key concepts are having a continuous underlying array, using a shape
slot that can reshape to any other shape with the same product without
chang

The tuple is defined ...

The idea is to store an n-by-m matrix as a flat sequence, instead of an
array of arrays.
To accomplish this we map element subscripts, (row, col), to a singl
