John,
Well, let us iterate the libraries which were presented this C++ Now conference which are not in Boost and have no (to my knowledge) intention to enter Boost. Some of these may not be C++11, it was hard to tell from the talk description, but a majority were:
* Octopus
Unable to find that one.
It's here: https://github.com/STEllAR-GROUP/octopus. However, it's currently not in good shape as it relies on some older version of HPX.
* HPX
From a well known Booster, depends on Boost and is Boost-licenced. Let's hope we see it here soon, although it looks like it may still be experimental?
HPX (https://github.com/STEllAR-GROUP/hpx) can be seen as a maturing experiment :-P (HPX gains traction as it now can be used as a backend for Boost.Odeint and Joel Falcou's NT2, using it as the backend RTS for OpenMP, MPI, and OpenCL is in the works, other systems are under consideration to be supported) In order to be usable on real machines out there (administrators of supercomputers are notoriously conservative) HPX is written using C++03 with some C++11 features (mainly rvalue refs and move semantics) as supported by a reasonable set of compilers (gcc >= 4.4.5, VS2012, etc.). It heavily relies on Boost where the implementation is not sufficient or adds its own replacements where needed (movable/serializable tuple, function, bind, any, etc.). However, all of HPX's API is closely aligned with C++11, where possible, which clearly simplifies adoption. In any event, we don't expect HPX as a whole to be considered for Boost any time soon for 2 reasons: a) it is written using C++03 (for the time being, might change as compilers catch up) and more importantly b) it is a library consisting of many sub-libraries itself (threading, networking, algorithms, data structures, serialization, facilities for distributed computing, etc.) and we don't have the manpower to extract pieces which could be submitted to Boost. However, we'd welcome interested developers to extract what looks interesting and submit it as their own.
Well it would be nice of some of those library authors could chime in with their thoughts, otherwise we don't really know one way or another?
