We have announced only core language feature completeness, the library

support is still meant to be experimental because of the ABI issues,
where we know we'll need to change std::string, std::list etc., but
are waiting for Dodji's ABI verification stuff before we are confident
we can do all those changes safely. Jakub
That's a good point. But then both the announcement should be *much*
more explicit that it only talks about the C++ front-end, not library
(IMHO certainly isn't, and that's a rather serious issue) and
c++0x_warning.h should be much more explicit that it refers to the
library, not the front-end, as regards the experimental bit.
