Alternatively, you could reimplement it, figuring it inside out. In this talk, Oleg will do both. He will walk-through a straightforward Haskell implementation of (dependently) typed functional language. He'll use simple, yet powerful libraries and techniques to make code clean and understandable. On the other hand, he'll add features one-by-one, and reflect on why and how their Haskell counterparts differ.
