One tiny correction: > decorators are functions that take a callable argument and return a new callable there's nothing forcing a decorator to return a callable. A decorator _could_ return anything it wants. I don't know why you would want that, but Python won't stop you.

They also don’t have to act on callables, see @dataclass for instance.

  Classes are callable.

    You can abuse this fact with type hunting to get a ParamSpec of a class's __init__ arguments. But yeah type systems get weird at the margins. Your class is an instance of type which has a __call__ method which creates an instance of your class.
