> The only situation I can see this being a real problem is with the combination of addition and multiplication, because people are taught that multiplication has tighter precedence than addition as early as elementary school. A primary reason programming languages using infix ops and f(x) call notation are still more popular than lisp style syntax is because people learn these math notations at school. So doing anything to the syntax that requires people to learn something unusual short of turning it into s-expressions isn't a good idea.
