Haskell will be a vehicle to discuss programming in a pure functional language, and static, polymorphic type systems and type inference.
The Haskell lectures notes with a .hs extension can all be run in Haskell -- if you want to run them, download them, and if necessary rename them to have just a .hs extension (not a .txt extension).
