Mention Bifunctor/Traversable?
endgame opened this issue · comments
The introductory course does not mention Bifunctor or Foldable/Traversable. While covering all the standard typeclasses is beyond the scope of this course, the Bifunctor instance for Either and the Traversable instance for []are both extremely valuable. Maybe worth adding a note:
- to the run sheet (as something to bring up at the start of day 2, before everyone settles back into their own work for the day?), or
- one of the
README.mds (perhaps level04 when handling DB results?).
