Re: Cont, ContT and IO()

by Matthias Görgens-2 :: Rate this Message:

>> process' = foldl op True files

>> op False _ = False

Please pardon me. 'doit' should surely be able to do some IO:

> import Data.Foldable
> import System.IO
> process' = foldlM op True files
> op True file = doit file
> op False _ = return False

were DoIt has the type FilePath -> IO Bool
