Probably you need only the 'pprint' and '(===)' functions from the "Data.PPrint" module.
.
Usage examples:
.
> pprint [1..]
> pprintTo 10000 $ repeat [1..]
> pprint $ iterate (*10) 1
> pprint $ map length $ replicate 5 [1..] ++ repeat []
> pprint [2 `div` 0, error "xxx", 18, 4 `div` 0]
> [1..10] === reverse [10,9..1]
> [1..10] === reverse [10..1]
> reverse [10..] === [1..]
> [1..] === [1..99] ++ [101..]
> ([1..], [1..]) === ([1..], [1..100])
> (error "x", [1..]) === (0 `div` 0, reverse [1..])
> error ("xx" ++ show (length [1..])) === 1
> error ("xx" ++ error "yy") === 1
> (error $ unlines $ replicate 300 "xxxxxxxxxxxxxxxxxxxxxxxxxxx") === 1
> pprint ['a'..]
> pprint $ "hello" ++ [error "x"] ++ "world!"
