I don't think you'll ever find this kind of code in production. With years of Haskell experience, I rarely encounter code that is hard for me to read. This is a good counter-example, and is not typical code. I read 10 lines of Haskell code roughly as fast as I read 10 lines of Python code -- yet the 10 lines of Haskell code can pack much more useful information. So Haskell is a great tool for more efficient communication between programmers, who can write shorter messages to each other to convey the same information.
