Modernizing Haskell Code Without Breaking Backwards Compatibility

This post is a bit of an iceberg. If you want to get the most out of it, here’s some challenges:

• Figure out how all of the code works. A few bonus points for doing it without running the code, a lot for no copy/pasting
• Find the breaking changes. The claim of backwards compatibility isn’t fully true. I’m aware of at least a few problems, there’s likely more
• Win $1000 and use the flamethrower. You probably need to be on desktop for this one, sorry
