+Updating fields of nested records is kind of annoying in Haskell. One solution
+is to use [lenses](https://wiki.haskell.org/Lens).  Implement several record
+accessing functions using lenses, you may use any library you want. The test
+suite also allows you to avoid lenses alltogether so you can experiment with
+different approaches.
