And FP developers in general tend to push conciseness to an extreme, especially with this kind of shenanigan (from the very source you linked):
import qualified Data.ByteString.Lazy as BL
It's ironic that after all this obfuscation, the author of the source still finds it useful to do ASCII art and align everything neatly. Talk about misplaced effort.
Pretty sure that’s done automatically like go-fmt or other similar tools. It’s zero effort and makes it easily to read. Also lots of languages have that import syntax (python import pandas as pd).
