Requires that the metaclass is ABCMeta or derived from it. A

The abstract methods can be called using any of the normal
'super' call mechanisms.

This defines a read-only property; you can also define a read-write
abstract property using the 'long' form of property declaration:
class C:

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()).
