But we're not talking about *real* intervals - we're talking about "intervals"
of (exact) integers. Do mathematicians use the term "interval" for sets
restricted to consecutive integers or cartesian products thereof?
The term "shape" or "array-shape" is used by SRFI 25.
The work "shape" is also used by Racket, NumPy, and APL, though since all
only support lower bounds of 0, their shape is a simple vector.
