BTW, there were some similar movements in C++ community, try to google for "MOJO Alexandrescu" or "Hinnant r-value reference".
First one is done using current C++, but has the exactly the sortcomings we both have encountered.
Second one is C++0x proposal, unfortunately it missed the composition issue... so very likely no help from there either ![Smile](images/smiley_icons/icon_smile.gif)
In the end, the best help comes from MSC compiler bug that actually allows binding temporaries to non-const references, so it is possible to define pick_ empty for MSC and detect at least some cases.
All of that said, maintaining pick semantics is much easier than it might seem. Yes, from time to time I do encounter "pick assert failed" (runtime enforcment of pick semantics in debug mode), but generally, effort is quite simple to get things work...
