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:
* Versor
Interesting, if very domain specific.
* Turtle Mock * BoundedInteger * Mach7
Currently has no docs on the web, so I can't judge.
* Octopus
Unable to find that one.
* 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?
* Metashell (or rather its underlying libraries) * libcppa (though Boost.Actor which is based on this is expected) * CppComponents
Interestingly also Boost-licenced, and from a Boost contributor.
* Some sort of C++ idiomatic XML library * Doppl
Couldn't find it.
* sfrp
Need I say any more?
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? Regards, John.
