I've been thinking the same, and also that we should consider putting
the C++0x versions in an inline namespace, so they mangle to a
different symbol, so that C++03 std::list and C++0x std::__cxx0x::list
can co-exist in the same programs and libraries.  I haven't had time
to experiment with that idea.
