It seems my answer to Oliver wasn't clear enough. This is not a problem of Boost.Move, but a simple programmer error in "X X::create()" that would have a significant performance penalty even if the compiler/linker would accept the code.

However, a CRTP class might be used to convert between the optimized mode with unhappy assignment operator signature and the non-optimized mode.
