C++11 has been finalized for almost two months now! And there's almost one compiler that fully supports it! That's enough time and products for everyone to re-evaluate their experiences with C++!

Seriously, C++, even C++11 is still a mess. Compiler error messages relating to template use -- including the standard library -- are unhelpful at best, except for very recent Clang builds. Compilation time when you actually use what the language has to offer is measured on a geological time scale. The footprint of the generated code, more often than not, makes I-caches cry. You'd be amazed how much faster your computational code runs when it fits properly into an I-cache.

I moved back to plain C a few years ago after having used C++ intensively since '94 or so -- and I'm not looking back. Yes, I do write ~10% more code; it compiles instantaneously, is easier to reason about and to debug, and usually runs just as fast.

I haven't had a chance to try the newfangled C++11 features, but I'd be surprised if they'll make a difference for me.
