​I'm all for improvement but obviously if it was that simple you would have
just proposed the desired wording and asked someone to commit it. I was
trying to understand (and communicate my understanding) why it wasn't done
better in the first place.

Beyond that there is still the need to teach the user the correct syntax of
these functions - and not only point out when they get it wrong so they
blindly fix their typo - in order to better avoid the situation where the
syntax is valid but the outcome is unexpected. Two separate problems of
which the later seems more important than the former - and probably
somewhat easier to implement.
