That seems unnecessary to me unless BINOP_DIV and your BINOP_FLOATDIV
have different meanings in Pascal? Otherwise, I think the problem is
that the pascal language needs its own expression evaluator so that
it can handle the '/' operator specifically. The rest can be delegated
to the standard expression evaluator.

Ada does, but it's an overloaded operator, so the type of the result
depends on the type of the arguments. Don't know about the other
languages.
