I heartily agree. Once again I must emphasize that in the hands of a poor
instructor, either notation is a dangerous thing. It is very naive to
think that notational innovations can substitute for careful language. I
agree that if there is an improved notation we can all agree on, and to
which the entire discipline is willing to turn, that we should introduce
it to the students. But function notation is not the answer to every
difficulty with teaching calculus. Rather, it can sometimes stand in the
way of understanding. IMO, a judicious mixture of the functional notation
and variable notation is the best.
