The simple answer is: since the class doesn't exist yet, you cannot
refer to it. The class name is just a regular name:
py> MyClass = 'something else'
py> class MyClass:
so the interpreter would need to provide some special-cased magic inside
the class body to make it work as you expect. That may be a good idea,
but it is a separate issue from this.
