A Python base class that provides various decorators for specifying promises relating to inheritance.
It provides the decorator ``overridable``, which indicates that inheriting
classes that define this method
* must decorate their method overriddes with ``overrides``, and
* must call super within their method definition::
class A:
@overridable
def f(self):
return 0
class B(A):
@overrides(A)
def f(self):
return super().f() + 1
It provides the decorator ``implements``, which indicates that a method
implements an abstract method in a base class::
class A:
@abstractmethod
def f(self):
raise NotImplementedError
class B(A):
@implements(A)
def f(self):
return 0
