Have you tested this? I don't see the precedence issue happening here. Could
you try duplicating these reults with code explicitly specifying the precedence
you show? I do not think you are going to find that the outer parentheses you
show represent the actual precedence. Remember that the ? and : are not
different operators, but different parts of the same operator. If the +=
operator has a higher precedence than ?, it will also have a higher precedence
than :.
