I think you might have missed a couple modules (or maybe you left them off your list intentionally because there's something wrong with them such as being too out-of-date to use).

See http://www.prowiki.org/wiki4d/wiki.cgi?Phobos/PosixGetOpt for the fullest list that I know of.

I agree that one of these should be added to Phobos. I don't know which one (since I haven't studied the code of any of them or even tried to use any of them yet), but it's obviously a common problem. And Phobos should be there to solve our common problems. People can still use their own version if that's what they like, but Phobos should have at least one implementation.
