These slides are confusing!

Initially I read the line The object will appear to change its class and had the same idea like salva to simply re-bless an object into a new class.

But the shown mixin code seems to operate on classes not instances (just like roles in Moose do) ?!?

Could you please elaborate what you're exactly intending to do?

UPDATE

seems like I found the answer on my own:

Similarly, Object.extend(module, ..) adds the instance methods from each module given as a parameter. However, extend adds the methods to one instance, not to all instances.
