If he's just mucking around to get a feel for the language then there
probably isn't a better type. So a trite subclass of "object" is the go.

Just a brief aside for Harvey:

I spent a brief while confused that this doesn't work:

  o = object()
  o.x = 1

and that I needed to do this:

  class O(object):
    pass
  o = O()
  o.x = 1

until I realised that plain "object", the root of all classes, doesn't
accept arbitrary attributes. But subclasses do.
