Logic is a little tweeting bird chirping in meadow.
Haskell represents purity and freedom for many functional programming purists. It’s rich and powerful, but the power comes at a price. You can’t eat just a couple of bites. Haskell will force you to eat the whole functional programming burrito. Think Spock from Star Trek. The quote above is typical, embracing logic and truth. His character has a single-minded purity that has endeared him to generations. Where Scala, Erlang, and Clojure let you use imperative concepts in small doses, Haskell leaves no such wiggle room. This pure functional language will challenge you when it’s time to do I/O or accumulate state.
