for over 20 years, I tend to think that I know how to distinguish a binary
operation from something else. And in my (not so in this case) humble
opinion I think that exponentiation is a binary operation in this case.

Ever heard about {{{exp()}}}? Exponentiation is a jolly good binary
operation on positive real numbers.

Try to convince a beginner that the inconsistencies that got this ticket
started are OK, without saying that Sage has not made a good choice.
