Hi to all, Are you a C++ expert? Do you like Boost.Move? I have a challenge for you. During Boost.Move review, Jeffrey Lee Hellrung suggested adding "techniques to capture (implicitly created) rvalues with emulated rvalue references in C++03, e.g., for push_back, when you have knowledge of the types of objects you want to capture". I've worked on this problem these days and the solution is less than obvious (several compilers have has problems with ::boost::is_convertible and non-copyable types). I found a solution (attached test and required boost/move/move.hpp header) after several tries but it's complex (it needs several overloads and enable_if tricks) but I'm sure boosters will find a easier solution ;-) Current solution seems to work on these compilers: MSVC 7.1, 8.0, 9.0, Intel 11.0, GCC 4.3.4, 4.4, 4.4 c++0x mode, 4.5, 4.5 c++0x mode. Problem: MSVC 10.0 (Visual 2010) with real rvalue references seems to have bugs and does not compile the test. I can't find a workaround, a future Service Pack might solve these errors, but maybe we should stick to emulation code in this compiler, unless someone could shed some light on this, of course. Waiting your proposals, Ion
