-When the replacement list has an expression, it is recommended to surround
-it with parentheses. This ensures that the macro result is evaluated
-completely before it is used.
-
-It is also recommended to surround macro arguments in the replacement list
-with parentheses. This ensures that the argument value is calculated
-properly.
