Thanks!
There is no specific goal, i am in process of building pattern knowledge
in python by doing some examples.
Not all patterns are useful. Just because it's been enshrined in the
GoF patterns book doesn't mean that it's good for Python.
I don't understand why you would like a class to pretend to make new
instances, but actually lie and return the same instance over and over.
It makes them impossible to test: your unit tests all act on the same
object, there's no way to start over with a fresh object.
If you only want one object, create just one, and use it everywhere.
