"I've seen experienced programmers failing at learning Haskell...the initial learning curve is very steep, and they don't see the value on climbing that wall...with Haskell, all those seemingly complex concepts come with a big reward." [1] [2]

My question is: I currently don't see the value proposition of learning Haskell. What is this great enlightenment I'm supposed to receive from studying Haskell? Can someone give me the TLDR version?

PS: If you say "functional programming", please elaborate. I know all about function pointers in C, and I've read the docs of Python's functools module [3].

[2] I don't want this thread to degenerate into a favorite editor flamewar the way the other one did, so I'm leaving out the commenter's clearly preposterous claim that learning vim is worth your time.
