My point was that adding parentheses around the tightest-binding
operator is a common, clear, and usually insignificant, way of
demonstrating operator precedence. So FOR THAT USE they must not
change evaluation of the expression. Obviously if you put them
anywhere else, they change evaluation. Nice job knocking down a straw
man.
