Re^2: Golf: Length of longest line in a file

[ambrus]

Wouldn't getContents from the prelude work instead of IO.getContents? This shortens a lot because now you can use ghc -e instead of runhaskell, eg.

#!/bin/sh
ghc -e 'getContents>>=print.maximum.map length.lines'

We also use some other functions of the Prelude for brevity. Note that the code can't be in the same argument as -e.
