[Haskell-cafe] Soliciting feedback on my lens json parsing tutorial (please don't share yet!)

Hi All, I wrote a lens json parsing tutorial here: https://github.com/codygman/concise-json-parsing-in-haskell I'd appreciate any feedback. My approach tries to use a prior understanding of Python into understanding lens enough to do something useful. Perhaps I can include links to tutorials that cover more of the theoretical foundations as well. Any criticism and/or ideas is welcome! Thanks, Cody Goodman
