I would be wary of using any language that was not yet backed by a standards body such as ANSI, ISO or ECMA. That is perhaps an indicator of maturity. That said Java and Delphi for example would fall into that category, and while I do not use those languages, they could probably be described as "mature".

Another measure might be the number and quality of books and articles written for the language. There is one book for D that I am aware of by Andrei Alexandrescu. He has also written a long article on the language for Dr. Dobbs, where he specifically deals with the standard library issue.
