I'm not sure where constexpr is but lambda is moving right along: Check 
it out here: http://gcc.gnu.org/viewcvs/branches/cxx0x-lambdas-branch/.  
I've built and run some interesting cases with lambdas.  They may be 
waiting to see what the next draft of the standard looks like after the 
concepts fall-out.

The new library components are experimental but not 'very'.  They should 
be usable and we would really want people to use them and report 
problems.  They are checked in with test cases that should pass.

Personally I haven't used the thread and future, etc libraries much.  
I've used all the containers in programs.  I've used random.
