Generic is a library for [Generic programming](https://en.wikipedia.org/wiki/Generic_programming), also known as [Multiple dispatch](https://en.wikipedia.org/wiki/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

|
|
excellent readthedocs.org project. Development takes place on
