But we don't follow that rule.  If we did, we'd have to
write macro definitions like this:

  #define foo(x, y) bar ((y), (x))

with the extra parentheses; which we typically don't do.

Of course it's a minor point.  There's a style where one always
parenthesizes the operand of "return", e.g., "return (x);".
For people used to that style, it's weird to see "return x;" and
at first it looks like a mistake.  But one gets used to it...
