Not so; there are two distinct uses of sizeof:
	sizeof unary_expression
	sizeof ( type_name )

The former does operate on an expression; however the expression is not
evaluated (so no side effects occur), only the type of the expression is
relevant.

A particularly simple form of unary expression consists of just the
identifier for an object, but more complex expressions are permitted.

Now that you got right.
