There are some languages that tempt more abstract navel gazing than others. I’m not sure about Haskell, but Scala tends to do that. Anyways, there is something about human behavior and language design that can lead “more is less” situations.
If you don't have a use case creating a need that your program solves, what's the difference between figuring out make a zygohistomorphicanedoreticular for polynomials and writing a working library that no one uses? Either way, you do whatever is fun for you. If you have an actual customer requirement, then that guides your prioritization and attention?
