Usually, casts are the back door, but I don't believe that works in this case.<br><br>There's always this middle ground: taking the address of a ref could give you a void*. That way you really can't do anything unsafe with it without a cast.<br><br>Heck, with this trick you could even allow SafeD to take the address of anything. You wouldn't be able to do much without a cast beside comparing and printing addresses, but even that could be handy for debugging and checking for aliasing.<br><br>-- <br>Michel Fortin<br><a ymailto="mailto:michel.fortin@michelf.com" href="mailto:michel.fortin@michelf.com">michel.fortin@michelf.com</a><br>http://michelf.com/<br><br><br><br>_______________________________________________<br>dmd-beta mailing list<br><a ymailto="mailto:dmd-beta@puremagic.com"
