ipprint
Tiny helper for pretty-printing values in ghci console.
Usage example
>Prelude> let e = replicate 5 [1..14] -- value we want to print
>Prelude> :m + IPPrint
>Prelude IPPrint> pprint e
> [[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14],
> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14],
> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14],
> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14],
> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]]
