(typename)(expression) has one operator `(typename)' and one operand
`(expression)'.
The reason the type is enclosed in parentheses (as a design decision)
is probably to avoid ambiguity, consider this:

int i = 1; /* define and initialize i to 1 */
{
  int i; /* cast i to int, a statement with no effect, or define i in
block scope? */
}
