Currently, arguably, the most interesting one is that created by Walter Bright. This language aspires to take the positive features of C, C++ and a few other Algol syntax based programming languages, and to drop the negative features.
A reference document of the language can be found at " class="external">http://www.digitalmars.com/d/index.html Two things that differentiate D from C++ are that it does not have multiple inheritance and that it has an inline assembler.
The inline assembler is typical of the differentiation between D and application languages like Java and C#. An inline assembler allows a programmer to enter machine-specific assembly code alongside standard D code -- a technique often used by systems programmers to access the low-level features of the microprocessor needed to run programs that interface directly with the underlying hardware, such as operating systems and device drivers.
Unlike Java, D does allow the programmer to overload operators.
