One example is a page which consists of many different "boxes", each
associated with a different role. I solve it with Cells at the moment.
Each cell extends the object. I think it would be good in this case to
unextend the object after the cell finishes rendering.

Another example might be a Rails app which doesn't use Active Record but
keeps objects in memory (like Madeleine). In this case the object is
already initialized and if we don't unextend the role then we will have
most of the roles mixed after some requests.

Mixology gem can probably help here.
