| binop | | abstract public Value binop(int op, Value l) throws ValueException(Code) | | Two-level virtual operator dispatch. Each subtype implements the
same basic template for this abstract function:
Value binop(int op, Value l) {
return l.binop(op, this);
}
Then, type overloading allows for each type to implement all
ops for which it can be the left hand side for all allowed types
on the right hand side:
Value binop(int op, ValueInteger l);
Value binop(int op, ValueLong l);
