| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

| | | | | | | | comparisions have been made as string comparisions, even in cases where both operands clearly qualified as integers. The fix is to make the parser properly analyzing whether an operand is a valid integer or not.
