FTR: /me approved to CUFP, despite great reservations about content, and a strong temptation (resisted) to downvote it.

I did so on the belief that leaving this sit out there in limbo may be a disservice to some future reader interested in the uses of map here. Hence, it's now approved (subject to consideration or removal by the deities).

Note, by contrast, AM's post re HAL has also been indicted (in that case, in the CB)...but following the same logic, I've also approved that... and, in that case, ++ed it as "instructive."

Instruction may or may not have been OP's intent, but the intent has little bearing on its (marginal) value.
