That is a close definition, but it doesn't quite match if f has
different attributes than Function.

I could possibly write a MakeExpression rule that would approximate @
(using another character without a built in meaning, obviously) in a
notebook environment, but I don't (think I) know how to write an
approximation for a console environment.
