Is there an opportunity here for Boost.Containers to provide a 
std::list replacement that keeps the old O(1) splice and O(N) size?  I 
can imagine a lot of demand for this once people discover that their 
old splicing code is trashed by a std library upgrade...

[OT: does anyone know of a list of "C++1x nasties" like this?  It's 
easy to find lists of new features, but harder to find lists of misfeatures...]
