There are quite a few ways to do what you're describing (and no particular
prescribed way). You want to look at multimethods and tag hierarchies.

Tags can have multiple parents.
I'm working on a project called Spinoza (search the mailing list for that
and CLJOS) w
I'm not sure I would call that a mixin -- really, all that's going on
is Python is allowing you to call any function, anywhere. In a
language like Scala that does have what I'd consider "real" mixins
(traits over there), then on_key_down would become a function
available in TableWidget's
I'm trying to re-implement some python stuff in clojure. Here's how
it works: I have a class called ArrowKeySelection. I use this class
as a mixin with various gui classes. The class adds some abstract
logic for handling keys - the arrow keys move a selector around a
matrix and the enter key
