[Haskell-cafe] Compose

Hi sumSquareEven = (sum.map (^2)).filter even I wrote this thinking i was being very clever. The question is asking to spot the error in f = compose [sum, map (^2), filter even] I've only seen [] used in list comprehension and initialisation. I conducted a mini search on compose earlier but to be honest it just made matters even less clear. So the question is, does compose as a function or keyword exist in Haskell and if so how can the above code frag be corrected? O and, is compose in any way related to curry and uncurry? Thanks v mucho, Paul
