But I have a question on the constructor: why doesn't it take a T*&& parameter? explicit unique_ptr(T*&& p); If I understand rvalues correctly that would mean: unique_ptr ui(new int); // Ok int* pi = new int; unique_ptr ui(pi); // Not Ok In current implementation we have int* pi = new int; unique_ptr ui1(pi); // Ok unique_ptr ui2(pi); // Ok, but no good same applies to operator=() and reset(). / Jonas --- [ comp.std.c++ is moderated.
