C++0x is done.

This information is a couple of weeks old already, but it was new to me, and I suspect, some others on this board too.
The committee is done with the technical changes, and has signed off on the standard.
The Final Draft is available
here.
With some red-tape stuff pending, the official standard is expected this summer.
Thanks for the hard work, guys!

Good Job. I'm also waiting for ES Harmony. After that, I won't be able to tell which I'm going to use if I ever write an userspace app.
Maybe JS with inline ASM and static compilation?

Is there any good feature for who writes operating systems?

Will C++0x save C++ or is it another step into "inverbosibility"?
D language is nicer but as long the toolchains are mainly C/C++ I'm stuck with C++.

There is no need to mention D in a C++ thread. Or git in a svn thread. Or maven2 in an ant thread. People - or languages - don't need "saving".

I must say they did a splendid job of bringing C++ more up-to-date with the new features. Lambda expressions make it much easier to e.g. search through containers and operate on them. I've also found the auto keyword to be particularly useful where you usually have to write long iterator types.
Other features like nullptr are useful in situations where ambiguity might exist (much like C's NULL), but I have yet to encounter such a situation in my code. I've also noticed the custom suffixes and unicode support, which look very promising, but the compilers don't support all of them (yet).
Does anyone have experience with the range-based for-loop (a.k.a. foreach)? It looks suprisingly like Java's one.
PS: Quite a few people told me that C++ is a dead language, it's no longer used, and so on (they couldn't be more mistaken), I guess this pretty much proves them wrong. A lot of newer languages are nice, but I still believe C and C++ give a more "down-to-the-bare-metal" feeling when using the language. It also forces you to know what you're doing (e.g. when using pointers and dynamic memory allocation).

Does anyone know if C++0x support is going to require any more work with the ABI? Most of the features seem like they would be all compiler-side, and obviously the standard library improvements are irrelevant to a freestanding code base, but there might be something that requires some work to get supported in kernel code.
As far as 0x's features go, I'm particularly interested in lambdas and variadic templates- tuples, a strongly typed printf, a host of functional programming... all you need is monads and list comprehensions and C++ has EVERYTHING!

It shouldn't require any more of a runtime library than C++03 does. That said, features like lambdas are probably going to need you to implement stuff like std::function (<-- which itself requires the heap) to use in a lot of situations.

I know this thread is slightly old but I really felt the need to throw my two cents in on this point. In my experience, the whole C++ is a dead language thing is something you hear from Java or .NET fanboys who don't know jack about programming and who are completely dependent on WYSIWYG form editors and code generation tools.

+1.
Ask them which language their JVM or CLI is written in.
Don't get me wrong. Java and C# are good languages when you have to develop code for the customer. C++ can be used for this, too, and would certainly be even better if a big company like Sun or Microsoft had a native interest in pushing the language and its tools. (Remember: Java and C# both have enjoyed a multi-million-dollar marketing budget, something C++ never had.) As it is, C++ wouldn't be my first choice for that.
But that's not really where C++ "rulez", either.
It's the frameworks themselves, and the core code where managing your own memory is more or less required to get any kind of acceptable performance.
"Virtual" languages are A Good Thing, and certainly superior in the RAD department, but there are other areas where they just don't cut it.
C++0x is a great step forward for the biggest, ugliest, most powerful beasts among the programming languages. It won't wrestle world dominance away from Java or C#, nor does it intend to, but it does give more power to those who used it to bring you Firefox, OpenOffice et al.

I've been missing C++ lately, especially since watching these:

Lambdas give C++ so much power... I wish they had been around four years ago when I really needed them.

Isn't Firefox [predominantly] in C, and Open Office in Java?
