OK, so clang 3.1 will be on the list (in C++11 mode). N3276 is a necessary condition for turning on decltype-based result_of by default. It seems unlikely that gcc would introduce support by Sep 17, but I'm not following their develop schedule at all. I think it's OK if clang and (presumably) msvc are the only compilers that get the change this time around. If someone finds out more about gcc's progress, please let the list know.
