Example please? (Non-programmer here; I'm sorta familiar with s-exprs but can't quite picture what you have in mind.)

  In Lisp, operators and function calls are all prefix, so this would be subtraction: (- 10 5) I think (it's been awhile lol). A hyphen anywhere else wouldn't be confused with subtraction. This is just a guess though.
