There's an exception safety issue. Which is a pity as other than that it seems fine. I'd assumed that support would be pretty good on all C++11 compilers, so I made it an 'all or nothing' feature, partly because there are issues with pre-C++11 allocators, but this suggests partial support might be desirable. Not sure I'll be able to (or want to) put the time in though.
