Code written in Haskell is often really easy to pick up. Due to it's pure functions it can easily be picked up function by function and the GHC repl gives you an easy but powerful way to poke around. Of course there are also the crazy type level EDSL libs which are hard to disect, but in general Haskell has been the best language for me to pick up code written by others.

Maybe, I'm a bit skeptical, but I'm not a very good Haskell programmer.

I see too much symbol soup and point-free style makes it tougher to understand the code.
