If you do not want to deal with move emulation (which I've found very brittle in complex expressions), a simple way to to gain the advantage of T::operator=(T rhs) even when assigning from lvalues is something like:

templateT destructive_copy(T& x) { using std::swap; T result; swap(result, x); return x; }

which relies on NRVO to eliminate expensive copies:

Shouldn't the last statement be return result; instead? Or maybe I am missing something? Best Regards, Gevorg
