Fraid so.  Sizeof is an *operator*, which can (but does not have to be)
invoked with a function-like syntax.  If foo is a variable, "sizeof foo"
(note no parentheses) is legitimate.  The parentheses are necessary for
syntactic reasons when the operand of sizeof is a type -- and if you
think this is easy to parse, you should try it sometime! -- but they
do not make sizeof a function.
