Abstract
========
This is a proposal to add Abstract Base Class support to Python 3000.
This is a proposal to add Abstract Base Class (ABC) support to Python
3000. It proposes:
* An "ABC support framework" which defines a metaclass, a base class,
a decorator, and some helpers that make it easy to define ABCs.
This will be added as a new library module named "abc".
* Specific ABCs for containers and iterators, to be added to the
collections module.
* Specific ABCs for numbers, to be added to a new module, yet to be
named.
* Guidelines for writing additional ABCs.
