Well, these one-letter functions do consume namespace, but most one-letter variables are uppercase anyway. Good idea would be forbidding redefining them. On the other hand, Emacs makes most unicode symbols look terrible and other editors don't support unicode input at all.

I already use ≤≥, because <> are used as lambda, and still consider using usual eq/lt/gt.. instead.
