1- Are you sure that you want that behavior? Given that in python, a class is
just a particular case of invocable object, you could just write a function
instead, and the code may be more robust.
2- If you are /sure/ that is the behavior you want, take a look at the __new__
method. The __new__ can decide which instance to return (you could even define a
new class inside of it, instantiate it, and return the instance).
3- You may want to take a look at metaclasses. But without more details about
why you want it, I can't give you more precise answers.
