D is pretty nice. It has implemented almost everything people suggest when they mention how to fix C++, but it has some major problems as well. It'd have to be supported by a lot of different vendors on different platforms and architectures, and the standard library would has to be straightened out.

What I was proposing is a C++ compiler that could enforce a specific subset of standard C++, along with making things that are generally regarded as best practices default. Because of the complexity of C++ it might have to be a somewhat simplified version of it to work (something like http://www.csse.monash.edu.au/~damian/papers/HTML/ModestProp...).
