Why would anyone willingly used Haskell?

Seemingly everyone's main complaint with Python is _FIOC, yet it doesn't give a shit whether you use tabs or spaces so long as it's consistent.

Try to use tabs when I damn well want to in Haskell, and it gives me an I DON'T THINK SO, TIM without feeding me the actual error. Good job, Haskell crew.

Is this your way of saying I have read SICP or do you actually know haskell ?
