Hello all!<br><br>I am wondering, why the type_traits do not have a construct to check if some type is copy constructible (I mean if the copy constructor is available (public) or not).<br><br><br>May be it can be implemented via calculating at compile time if some type can be copied or not... May be it is not possible at all. <br><br><br><br>With Kind Regards,<br>Ovanes<br>
