[Haskell-cafe] Newbie Q: GHCi: Where “List” module is imported from?

Going through "Haskell. The Craft of Functional Programming" book , in section 16.8 I found a Set module example. Module declarations starts with: import List hiding (union) "Set" module here is built with list and uses among other things list comparison functions such as (==) and (<=). For example: eqSet :: Eq a => Set a -> Set a -> Bool eqSet (SetI xs) (SetI ys) = (xs == ys) Q1: Where "List" module is imported from? GHC "Base" package contains "Data.List" module, not just "List" module. Besides, "Data.List" does not have (<=) function. Q2: Any tutorial on using GHC libraries out there? Thanks! Dima
