Forgive me for resurrecting an old thread - I found it in the "Best of 2008". I wouldn't have replied except I didn't check the date, and now it seems rather silly to discard my post simply due to that. I wonder, in the last six months has anyone's opinion changed?
The thing that really turned me off D was the fiasco with the "standard library", otherwise known as a mishmash of Tango and it's piddly little forerunner, Phobos. Once the two are completely integrated, I'd be interested in using D, but from where I'm sitting at the moment, there really isn't enough incentive to move from C++ which is far more widely used, supported and exemplified.
