The general guideline when writing classes (using the copy-and-swap idiom) is to provide a non throwing swap member function. (Effective C++, 3rd edition, Item 25 and other resources)
OK, so I\'m all sold on the copy-and-swap idiom and I think I mostly know how to implement it. However, or codebase uses MFC\'s CString class as string and this ain\'t gonna change.
If I have a class such as class Foo{ public: Foo(){...} Foo(Foo && rhs){...} operator=(Foo rhs){ swap(*this, rhs);}
For example, stdlibc++ has the following: unique_lock& operator=(unique_lock&& __u) { if(_M_owns)

In the beautiful answer to the copy-and-swap-idiom there is a piece of code I need a bit of help: class dumb_array
What is the copy-and-swap idiom and when should it be used? What problems does it solve? Does it change for C++11?
