As it turns out, that's a controversial question. ;-)
One answer: pedagogy (for those used to matrices).
A related answer: succinctness and readability of *some* code.

Matrices have the odd (and imo undesirable) property that
m[0,0] != m[0][0]
You want the former.

How do I access 1.2 in such a way as to end up with a float? I keep
getting a matrix.
