Do other people also **learn best by examples?** In the first part of lecture 8, Bartosz presents a simple example based very loosely on vertebrate anatomy. It could be a good exercise to develop this example into a more complete Haskell program, while keeping an eye on the tie-in to Category Theory. When learning a new programming language, in this case both Haskell and Category Theory, I learn best by struggling with a good example. In this case, it would be great to have knowledgeable people available to suggest and critique, similar to what you would expect if you registered for a week-long in-person course that included an in-depth all-day exercise. Maybe start the exercise with several Haskell lists, one for the blueprint and one for each of the models (human and dog)? And then what?
