I'm glad it works.

After some additional testing, this appears to be code that fails in
clang with -std=c++0x and -std=c++11, but works otherwise.  GCC 4.7
still seems to accept it for all -std options.

Possibly they have done something in the new C++ standard to
explicitly delete/disable this behavior.
