Unfortunately, cannot admit a library -- into a release -- that isn't being tested, so you need C++11 testers. However, that doesn't prevent you from putting it into trunk.

That's a reasonable tack.

Note that only means you may not get it into 1.51; it doesn't preclude putting it in trunk.

That's unfortunate. There will be many using C++03 for years yet.

Don't take this as policy, but I don't see any problem with adding a C++11-only library if your code is conditionally compiled to avoid problems with C++03 compilers (which could mean no code for those compilers). Trying to do so may reveal issues with config, but that will be helpful.

If you put it in trunk, C++11 testers are spun up, and tests go well, you might make 1.51. If there's insufficient time, try again for 1.52. Either way, keep seeking C++11 testers!
