I have tried to find some information on D. I do especially like this comparison with C++ to get an overview on what it is. Now I am asking myself: how often D is used in the field, and how much of a viable alternative is it to C++?
I think D is a great language, but what people might hold back from using it is that it is (afaik) not compatible with c++ libraries. So all libraries you can use have to be written in C or D. So if you are a C++ developer switching to D isn't so much fun.
