I'm trying to find the origin of the term, and whether there's an alternative names for it. All the usages I can find on the web point back to numpy manual. Any idea if it's been used before?
It originally derived from Yorick, an older array-focused programming language that many of the original NumPy (née Numeric) designers were familiar with.
