Yes, I disagree.  The only thing "sizeof" has in common with a "function"
(in the C sense) is that it is often written with the argument enclosed
in parentheses.  (Not always; I've seen "sizeof foo" many times.)  It is
a function in the mathematical sense, with a domain of "datatype" (though
it can also take an expression, which is essentially cast into "datatype"),
but I don't think that's what we're talking about here.
