So it fits what ESR says about Lisp?

"Lisp is worth learning for the profound enlightenment experience you will have when you finally get it; that experience will make you a better programmer for the rest of your days, even if you never actually use Lisp itself a lot."

Is that right? As Haskell seems to be far less intimidating to approach than Lisp, I may actually end up doing some. I fondly remember my junior level programming languages class and doing assignments in Standard ML. Haskell looks similar.
