For example a PEP 343 "Context Manager".

In the swamplands of the pythonistas the one-eyed man is BDFL!

No, for some extra flexibility there should be a NounKingdomEntererFactory 
-- which of course has to implement the AbstractNounKingdomEntererFactory 
interface. Instantiating the right NounKingdomEntererFactory can easily be 
delegated to a NounKingdomEntererFactoryProducer. It's turtles^Wfactories 
all the way down...

I don't know how this will ever do anything -- my theory is that some good 
soul managed to sneak a few lines of javascript into the giant xml 
configuration file ;)
