By this reasoning, we should use "while expr" instead of "while (expr)",
and "if expr" instead of "if (expr)".  And don't forget "switch expr" to
replace "switch (expr)".

My own opinion is that "return (expr)" is clearer, since it clearly
distinguishes between the keyword and the parameter.  I think of this as
a general "thing-to-do (thing-to-do-it-with)" syntax that is consistent
among C commands, functions, and macro pseudo-functions.
