      Can you make Bison happy by allowing

              '(' <expression> ')' <expression>

      as legal syntax, and then requiring that the prefix-expression denote
      a type? Off the top of my head, this should be OK, shouldn't make
      error reporting any more confusing, and even allows for future expansion
      of the language in the direction of type-expressions :-)

Consider (a) - b. Is this a cast of -b, or a-b ?
