Return a movable reference to the specified lvalue. This function is selected by overload resolution if the move constructor for t_TYPE is nothrow-move-constructible. Constructing a t_TYPE object from the result will result in the (safe) move constructor being invoked. Note that that the bsl::is_nothrow_move_constructible trait can be customized in C++03 mode to indicate that a type is nothrow-move-constructible.
