Yes, D is not a small and simple language. The goal as stated at DConf was to be "comprehensive". D shall include the right tool for any job in system programming. That necessary includes that the programmer has lots of options. You can use threads or fibers. You can meta-program with various degrees of freedom (and danger) up to generating arbitrary code strings during compilation. You can use high-level parallelism tools like parallel map and thread pools. You can explicitly use SIMD operation for instruction level parallelism. You can have a garbage collector or you can disable it. On the other hand, D fixes a few problems of C++ (which mostly come from C source code compatability) like ambiguous syntax for templates (Is ">>" a shift-right token or two closing "parens"?).
