The biggest argument for such a mechanism is that it should be more foolproof. I hope it causes a compile error if "array" turns out to be a pointer.
Yes, of course.
In that case, yes, it's very much worth including. Everytime I write sizeof(a)/sizeof(a[0]) I think "I know there's a better way to do this, but I don't have the time right now..." Libraries save us from that sort of cognitive dissonance when coding.
I've reattached an implementation I proposed here a couple of years ago. The reason why I'm asking is basically that it would require some "somersault" to make it work with VC6 and other broken compilers, so I woldn't spend time on that if there is no interest.
That somersault is easy enough (although I've forgotten what it was exactly, there's an easy workaround). -- Dave Abrahams Boost Consulting www.boost-consulting.com
