D is a compiled, garbage collected, general purpose system and application programming language. It supports three programming models: imperative (function + data), object-oriented, and generic (template metaprogramming); making it a multiparadigm language. It is higher level than C++, but retains abilities to write low level, high performance code, and to interface directly with operating system APIs, and hardware, via an inline assembler. D is well suited to writing medium to large scale, million line programs, with teams of developers. D is easy to learn, more so for C/C++ and Java programmers, has many abilities to aid programmers, and is intended for aggressive compiler optimizing. It maximizes similarity to C/C++ language, processes, and tools, except where backward compatibility interferes with productive coding and more efficient compiling. The effort is lead by Walter Bright, who wrote or co-wrote many respected programs.
