This is fairly interesting. MS have extended their C++ compiler significantly for Windows8 with a bunch of non-standard stuff. FINALLY implement garbage collection, ref counting, properties, delegates, events, generics, etc... If other compilers adopt this tech, D loses some advantages. Oh, and Andrei got a nice little name drop around 35 minutes ;)
