Animals is a class. Giving Animals a parameter (such as 1 or 'ant') should return the instance that matches. Animals is not a class -- it just uses the class syntax as a convenient way to set up the names used to construct the new type. (This subtlety is why the metaclass hook is reputed to make peoples' brains explode).
So Animals is a type? Like int?
--> int('5') # 5
--> Animal(1) # I think it should be Animal.ant ;)
This is how classes work. Not really. Normal classes, when called, give you a new instance: they don't look up existing instances.
You mean like bool?
