Of course, with libstdc++ symbols in the .so file are only a part of the
exported interface, due to all of the inlined functions.  Do we have a
way of segregating this likely-to-change functionality at the source
level so that users will not accidentally use C++0x capabilities?

It may even make sense to distinguish between C++0x in the compiler and
C++0x in the library, in the sense that I might want to use C++0x
language features without using C++0x library features, for users who
want to preserve the ability to link with older libstdc++.
