There *are* languages without any operator precedence stuff (except
parentheses).  APL, Lisp, and FORTH spring to mind.  (The last two
may not count as one doesn't write typical algebraic expressions.)

Another interesting(?) idea would be to base operator binding on
spacing:  expressions that "look" like they are done first, are
done first.  (This isn't my idea, by the way.)  That is,

	a <- b+c * 4

would be equivalent to

	a <- (b + c) * 4

(Personally I think this is worse than no precedence).
