That will be very helpful.
I am preparing material for an Algorithms and Data Structures course using
Python. I would like to demonstrate paradigm shifts in models of computation.
Earlier I had thought of using Haskell together with Python for some of this,
but it Would be great to stay within the Python world if I could cover the key 
computational monadic ideas without the rest of Haskell.
