For what it's worth, I never understood why Bjarne reiterated the name
of the class inside the class. I would have just had:

    class MyClass {
       construct() { ......... }
       destroy() { ........ }
    };

and I would have had "ThisClass" be an alias for the class name, something like:

    class MyClass {
       construct() { ......... }
       destroy() { ........ }

       ThisClass &operator=(ThisClass const &rhs) { ..........; return *this; }
    };

But because of Bjarne's decision: If I want to rename a class, I have
to do a "Find & Replace in Files" instead of just changing it in one
place.

If I look back over code I wrote ~20 years ago, I think I sometimes
did the following:

    class MyClass {
       typedef MyClass ThisClass;
    };
