How to “perfectly” override a dict?
...or out the difference between Python 2 and 3, create a singleton (_RaiseKeyError) to make sure we know if we actually get an argument to dict.pop, and create a function to ensure our string keys are lowercase:

Monad in plain English? (For the OOP programmer with no FP background)
