Forbid old-styled classes

In python2 we had different classes: class Some: and class Some(object): were totally different things.

Currently, we don’t have this thing in python3, but since these times I believe that new-styled classes are still better.

1. It has more semantics: this class is related to object
2. It has unified interface: class Base(object) and class Child(Base) vs class Base and class Child(Base)
3. Explicit is better than implicit

So, I believe we should ban classes with old-styled base class. General rule is: always write super-classes’ names

Correct

class Philosopher(object):
    def __init_subclass__(cls, default_name, **kwargs):
        ...

class AustralianPhilosopher(Philosopher, default_name="Bruce"):
    ...

class WithMetaClass(object, metaclass=MyMeta):
   ...

Wrong

class Philosopher: ...
class AustralianPhilosopher(default_name="Bruce"): ...
class WithMetaClass(metaclass=MyMeta): ...

Yes, both classes are subclasses

And good developer knows that. But you cannot clearly see the difference between these classes though.
