C, Objective-C, C++... D! Future Or failure?
TDRighteo writes "OSNews is carrying a quick introduction to a programming language under development - D. Features include garbage collection, overrideable operators, full C compatibility, native compilation, inline assembler, and in-built support for unit testing and "Design by Contract". With all the discussion about the future of GNOME with Java/Mono, does D offer hope of a middle-road? Check out the comparison sheet."
Looking at that comparison table, it's clear the author hasn't looked at Java since 1.4
D drops archaic C++ features like the preprocessor and forward declarations. It adds modern features like design by contract, unit testing, true modules, automatic memory management, first class arrays, closures, and a reengineered template syntax. D retains C++'s ability to do low level coding, and adds to it with support for an integrated inline assembler. C++ multiple inheritance is replaced by single inheritance with interfaces. D's declaration, statement and expression syntax closely matches C++.

Actually, the post was a bit misleading -- D only provides *link* compatibility with C. You can link to C libraries without any trouble, but you can't compile C source code in the D compiler.
It's seems that a lot of people are complaining about something that was seriously mis-reported. D CAN'T COMPILE C CODE!! (Sorry for shouting.. but I'm hoping to get peoples' attention). D can link to C binary code.. wow.. what a concept.. almost every programming language can do this. It's almost a requirement for any new language. Without it you would start with 0 code base, and no one will use it. The below text is taken directly from the article. Notice 'Binary Compatibility' and 'Link Compatible.'
Binary C Compatibility:
D programs can import and link against C code and libraries, providing D with free access to a huge amount of pre-written code. Note, however, that D is not link-compatible with C++, so pure C wrappers are required to access C++ code in D.
Personally, I've been praying for years for a language like this to get adopted. Why is it that I can only use full object oriented programming for web/network applications?! Sure.. I know you can do more than this with Java or C#, but is it really practical?? Usually it's just a massive drain on resources. If you need high performance, then you can't do better than C++. Unfortunately, C++ is a transitional language (just look at it's name..). A pure object oriented, fully compilable language that has no VM is desperately needed. I can't believe it's 2004, and such a thing still hasn't been adopted. I hope D (or something like it catches on.. As much as I loved it when it first came out, I'm sick of wrestling with C++ code.
