I'm not sure I understand the relationship between partial function and exception handling. Aren't partial functions just curried? One or more arguments are bound, but not all? At least in Python, if you partial-ify a function that raises an exception, it still raises. I don't understand if the author likes that behavior or doesn't. Maybe this is some Haskell implementation detail that I'm not aware of.
Last time I wrote any non-trivial Haskell was in 2014, so a long time ago, but I found that my biggest problem with it at the time was the really huge variety of Haskell in the wild. If you're doing simple stuff, you probably stick to the prelude and you'll be happy. But if you're doing anything that's a bit complex, you'll end up seeing hundreds of mini-dialects of Haskell in the wild, so much so that I found it really difficult as a newcomer to understand code on the net. In many cases it's almost like a different language completely, what with the user-defined infix functions, tons of currying everywhere, laziness, and the like, made it very difficult to follow code paths.
