C++11 Compiler: Closest to the standard and how close?

I'm interested in learning C++ more thoroughly now that C++11 is apparently ratified. What compiler currently implements the closest thing available to full C+开发者_开发知识库+11 support? How close is said compiler to full support? Are there still major features missing or just language lawyer minutiae?

There's a support matrix on the Apache wiki.

I think the one Scott Meyers maintains on his homepage is pretty good:

The llvm C++ compiler "clang" has partial C++11 support; you can see its current state at http://clang.llvm.org/cxx_status.html.

---

There's also GCC C++0x (or C++11) status page : http://gcc.gnu.org/projects/cxx0x.html

---

IBM's xlC++ compiler has a basic C++11 feature support page.

To anyone reading this now, as of Jan 2013 Clang 3.2 is probably the most complete C++11 compiler, although the latest dev branch of GCC (4.8.x) is going to bring GCC back on par by the looks of it.

Just look at that support table! Epic stuff. That's only accounting for currently available stable versions as well whereas the GCC table contains some 4.8 entries.

Like I said though, when GCC 4.8 hits stable release, it's going to be tight between the two again:
