Haskell: Inserting every line from a file into a list

Question

I\'m currently working on project with Haskell, and have found myself some trouble. I\'m supposed to read and insert into a list each line in a \"dictionary.txt\" file, but

Answer 1

Unless this is for homework or something, there's no reason to use so much effort. Reuse is lazy!

getLines = liftM lines . readFile

main = do
    list <- getLines "dictionary.txt"
    mapM_ putStrLn list

But as you seem to still be learning Haskell, it is important for you to understand what CesarB has written.
