Or perhaps, how not to do an observer pattern in Python...

Abstract base-class Observable: https://git.gnome.org/browse/mousetrap/tree/src/mousetrap/core.py?h=gnome3-wip#n59
Concrete class Loop that implements Observable: https://git.gnome.org/browse/mousetrap/tree/src/mousetrap/core.py?h=gnome3-wip#n76
Plugin interface (observer): https://git.gnome.org/browse/mousetrap/tree/src/mousetrap/plugins/interface.py?h=gnome3-wip
Folder containing concrete observers: https://git.gnome.org/browse/mousetrap/tree/src/mousetrap/plugins?h=gnome3-wip

Might be useful to a data structures or design patterns course.

We are considering alternative implementations, including swapping it out for a system wide pub-sub-pattern: http://en.wikipedia.org/wiki/Publish%E2%80%93subscribe_pattern
