Actually, there is no move emulation in Boost.Variant. It has that appearance though because it was written with move semantics in mind, i.e., there are hooks there to take advantage of (no-throw) moving should it become available. The code in the sandbox that Ion mentioned was my (aborted) attempt to provide emulation. Compared to my implementation, I think what Dave Abrahams has implemented (http://boost.cvs.sourceforge.net/boost-sandbox/boost-sandbox/boost/move.hpp) is better. I don't know how it compares to the implementation in the new threads library, though. Eric P.S. Does anyone know why is it that my changes appear in SVN and not Dave's? When were the contents imported from CVS at Sourceforge? On 10/26/07, Mathias Gaunard <mathias.gaunard@etu.u-bordeaux1.fr> wrote:

Can I propose boost/thread/detail/move.hpp for review as the basis for boost-wide move emulation?
I think there is also some move emulation done in boost.variant.
