Generic programming library for Python

Generic is a library for Generic programming, also known as Multiple dispatch.

The Generic library supports:

• multi-dispatch: like functools.singledispatch, but for more than one parameter
• multi-methods: multi-dispatch, but for methods
• event dispatching: based on a hierarchical event structure (event objects)

You can read documentation hosted at excellent readthedocs.org project. Development takes place on github.
