In C++ you can cast one class type to another if you override the
operator=
Then you can convert one class type to another...
In Python it would appear that the left hand side of the assignment
operator
is not used to determine if a cast is necessary.
So how would I do this in python?

a = classA()
b = classB()
b = a

In the end b would end up just being a refrence to a
no conversion would have been done.
