We don't know. nullptr is implemented in Clang, but we have fairly limited testing of this feature and so we don't know if the implementation is solid enough for us to advertise it as being complete.

If someone wants to write a bunch of tests for nullptr to verify that it's working well, we can turn on __has_feature(cxx_nullptr).
