You can't in APL or mathematics either. There is a tradeoff between expressiveness and enforcing code quality. The downside of giving meaning to otherwise non-meaningful expressions is that fewer errors can be caught by the system -- its harder for the user to detect a wrong result than to simply respond to an error message. _______________________________________________ No banners.
