[Matrix-SIG] [PSA MEMBERS] Numeric Python Set function

[Paul F. Dubois]

Since it is nice to have a positive answer to a question, I want to make
sure Zane's answer reaches the matrix-sig. Please excuse if you already saw
it.

Is this function, or others in arrayfns, something we should move into NumPy
proper? I think array_set does sound like an important function.
