Fortunately, they did not. It was decided that honoring parentheses would be the best way. Although there were originally some Committee members who opposed this because it inhibits useful optimizations, I hear that they backed down when it was pointed out that most such are still covered by the as-if rule. (E.g. |(i+1)-1| for integral |i| can still be reduced, since it gets the same answer under all conditions under which the original is legal.) Karl W. Z.
