ABCMeta
Metaclass for defining Abstract Base Classes (ABCs).
Use this metaclass to create an ABC. An ABC can be subclassed
directly, and then acts as a mix-in class. You can also register
unrelated concrete classes (even built-in classes) and unrelated ABCs as
'virtual subclasses' -- these and their descendants will be considered
subclasses of the registering ABC by the built-in issubclass() function,
but the registering ABC won't show up in their MRO (Method Resolution
Order) nor will method implementations defined by the registering ABC be
callable (not even via super()).
