[Haskell-cafe] Parse error

[Andrew Coppin]

Is there a specific reason why GHC consistently refuses to accept the 
following perfectly reasonable code snippet?

main = do
  putStrLn "Line 1"
  putStrLn "Line 2"

  let xs = do
    x <- [1..10]
    y <- [1..10]
    return (x+y)

  print xs

No matter which way I rearrange this, it *insists* that there's a parse 
error. This is very frustrating, given that it's utterly clear what I 
want...
