Yes, this sounds like a good addition to me.

I don't think we should do it for bits, as nothing in PHP really does do anything with that. If you want to do stuff with bits, I think the "bitset" package (http://pecl.php.net/package/Bitset) is the way forwards. cheers, Derick -- http://derickrethans.nl | http://xdebug.org Like Xdebug?
