/prog/ advice series: Haskell

Dear /prog/,

I'm tired of fighting with ENTERPRISE languages. I want to learn Haskell. The question is, where do I start?

I'm not completely ignorant of programming language theory -- I read http://mitpress.mit.edu/catalog/item/default.asp?ttype=2&tid=8184 several years ago -- but the math is a bit rusty. I've tried a few Haskell ``introductions'' but they were more philosophical wanking about the beauty of monads and other abstract bullshite than an instruction on how to program in Haskell. In short, help.

It's slightly better, but still sexual harassment.

GHCi, version 6.8.2: http://www.haskell.org/ghc/  :? for help

Prelude> let addNeg = (0-) . (+)

<interactive>:1:13:
    No instance for (Num (a -> a))
      arising from a use of `-' at <interactive>:1:13-16
    Possible fix: add an instance declaration for (Num (a -> a))
    In the first argument of `(.)', namely `(0 -)'
    In the expression: (0 -) . (+)
    In the definition of `addNeg': addNeg = (0 -) . (+)
Prelude> let addNeg = (0-) `((.).(.))` (+)
<interactive>:1:19: parse error on input `('
Prelude> let addNeg = ((.).(.)) (0-) (+)
Prelude> let compose x = foldl (.) ($) $ replicate x (.)

<interactive>:1:44:
    Occurs check: cannot construct the infinite type: a = a1 -> a
    Probable cause: `.' is applied to too few arguments
    In the second argument of `replicate', namely `(.)'
    In the second argument of `($)', namely `replicate x (.)'
