Python either already has various patterns implemented, or obviates the
need for them. For example, if you really need a singleton (answer - you
don't) just use a module attribute. Functions as objects and iterators
being so pervasive means that visitor and related patterns are just a
normal style of programming, instead of having to be explicit.
