It is! I yesterday compiled latest llvm/clang myself (surprisingly easy, by the way) to test how it would help our build times. We use a lot of C++ templates and gcc compilation times are a big pain point. I just ran syntax check with clang and it already found a bunch of pretty serious bugs, so it's not only faster but better at finding errors too.
they also mention now supporting objective-c++. that's got to be one strange beast to code in.
We do it daily. It's just a mixture of C++ and Objective-C code. I think quite many game studios are using Obj-C++ as their own libraries are in C++, but many times you need some interface elements from UIKit.
Nothing magical in Obj-C++, but there are a few dangerous ways to shoot your in the foot that you don't really learn by reading but by shooting.
LLVM is "sponsored" by Apple, who are keen to see good Objective-C support; Objective-C++ isn't really a combination of C++ and Objective-C, its more a compatibility option between different libraries and APIs.

Eh, I'd say that's even more misleading.
In the same sense that Objective-C is a strict superset of C, Objective-C++ is a strict superset of C++, adding the same features to C++ that Objective-C adds on top of C.
In practice, this means that you can mix Objective-C++ and C++ in the same file (but you can't treat C++ classes and objects as Objective-C++ classes or objects, or vice-versa).
this seems like a pretty big milestone. in particular, clang now has a libc++.
