When there may or may not be an automatically generated move assignment or constructor and the compiler may or may not choose a move based on the risk of an exception being thrown and with the return value optimisation etc it's rather difficult to predict exactly what will happen. Since this is a static decision it would be nice if the compiler could tell me. Otherwise I have to step through it in gdb to find out what method it is using. -- Anthony Shipman Mamas don't let your babies als@xxxxxxxxxxxx grow up to be outsourced.
