You could say the same thing about blank lines between code blocks, or spaces
around operators.  Newlines at the ends of statements are "semantically and
syntactically superfluous" too.

Remember that people (not just compilers) have to read programs.  If extra
parentheses make a piece of code more readable, then they are good.
