I think I have replied about similar requests before (not sure if it
was on these mailing lists).
In essence, at the moment we do not have any compiler & stdlib with
complete and stable ABI for C++11.
It is expected that gcc4.8 will break C++11 ABI to further implement
the standard.
Other non-default compilers also are fully featured at the moment
(w.r.t. C++11 compiler features).
Thus at the moment we cannot consider switching. One can compile with
C++11 enable where one must, but also one then gets to keep the ABI
incompatibilities down the road (boost / template libraries
especially).
While one would want to start using C++11, it's not default at the
moment and not feasible to make the default standard level C++11.
