The Case for D

Why not?
To summarize: 1) It is too high level for system programming and too low level for "enterprise" applications and web. 2) Maintains C-like syntax with most of its problems without C source level compatibility (just like Java and C#, btw). 3) Not stable (D1 vs D2). 4) Confusion with standard libraries. 5) Big and complicated (maybe not as much as C++ but not far behind).

I'm not sure what you mean by that, but the last I knew, one of the stated goals of D was that a piece of (working) C code could be fed to the D compiler and either it would compile and work as expected or throw an error. Such errors would be due to the "safety features" added to D to correct problems in C -- such as assignments in tests e.g.
if ( x = y )would cause a compiler error. -
If you are interested in getting familiar with the D programming language, here is a nice introduction[^] written by Andrei Alexandrescu (yes, the Andrei Alexandrescu :) ) Frankly, I am not buying it at all, but decide for yourself. Oh, and if you are going to read the article, be sure to click the "Print" link, or you will be flooded with ads.

Well, I just have to read the hello world program, and decide...
import std.stdio;
void main()
{
writeln("Hello, world!");
}If a language claims OOP and writes
writeln("Hello, World"), I know there is a problem. Best regards, Paul.Jesus Christ is LOVE! Please tell somebody.

D look interesting to me. I tried some examples and works great. But it is still in the early stage and it may take long time for people to accept a new language and start using it. If person like Andrei is writing about D, I am sure there will be something interesting to check it out. Here is what Walter Bright said on an interview[^] and I think he is right. C++ was (and is) limited by the requirement of legacy compatibility, and I thought much could be done if that requirement was set aside. We could have the power of C++ with the hindsight to make it beautiful. :)

Like C++, D allows free functions and member functions. So I don't see any problem here. Or am I missing something? :)

I've tried D out before and I quite like it, it's reasonably straight forward to code in without to many gotchas and the garbage collector is pretty good at its job. My only gripe was that in some places it can be a little to backwards-compatible with C/C++ especially with respect to dynamic memory management, but overall I like it. If you're on Linux then the GNU Compiler Collection has a D implementation (I seem to recall it was something like gdc) and should be in most of the repositories. Also Code::Blocks claims to support D as does Geany and GEdit does do syntax highlighting for it.

I'm "learn the C++ really good, then try other stuff" kind of guy. In the middle of the journey I turned to C# detour, but I'm slowly returning to the main road :). D is not my cup of tea, I've spent too much time on C++ alternatives and now I regret some of my decisions.

The idea is nice. But for my taste they moved to many advanced things into the language instead of the library. (Like dynamic arrays, hashtables, etc.) The case for string is different since it is always percieved as a basic data type in these days. What bothers me about this are unessecary incompabilities. In most C-anchestor-languages the append-operator for strings is "+". (c++,java,c#,...) And as long as there is strong typing and no implicit casts (like in c++) there is no danger of this. In D you use "~" for this as well as for appending some data to a dynamic array. But even if both is technically the same ("appending"), i'd rather liked dynamic arrays to stay "normal" classes, which can be derived or replaced if needed. And to make a clear distinction in code, i'd rather typed "myArr.Append(i);" instead of "myArr~=i;"

OT: but we bumped into Andrei in the bar at the end of this year's ACCU Conference[^], and he's a great conversationalist (expect to be challenged, and to end up laughing frequently). Definitely on my "interesting people to share a bar with" list. :)

Inherited from C, it is C++ after all :) Best regards, Paul.

Cay you say "multi-paradigm"? :-D

Isn't this plagiarism or at least a copyright violation? The D Language has been around for quite some time. [http://www.digitalmars.com/d/2.0/overview.html](<a href=)[^]"> They could at least have used to D#.
That's the very language the article is describing. Although it is worth noting that there were other languages with the same name in the past :)

Meh, they never claimed it was a "pure" OO language. If you want that, use SmallTalk :)
