[Newbies] Traits Example

Can anyone give me a simple Traits example? I am trying to figure out if it
would be useful for me in the context of developing Aida applications.
In Aida, a WebApplication observes a domain model object. Let's call it
Of course, you could subclass ANY object to create your WebAppModel, but I
still want it to know how to do certain things, like start and stop itself.
In other words, I might have one WebAppModel that subclasses Object, and
another that subclasses OrderedCollection, but I don't want to teach them
both how to start or stop each time I create a new one, and it seems less
elegant to subclass everything from a WebAppModel base class and then
include the actual objects they model as instance variables.
Does this make sense or am I missing some other fundamental concept, and is
this what Traits are for?
