How do I do logging in Haskell?

Question

I\'m attempting to use HSlogger to get some information about my program. So I add the following line to my function

import Data.Word
import qualified Data.Byte

Shameless plug: I'm the author of the co-log logging library. You can find the code of the library and tutorials on GitHub:

• kowainik/co-log

The details of the library usage and implementation are described in the following blog post:

• co-log: Composable Contravariant Combinatorial Comonadic Configurable Convenient Logging

Don't be afraid of a scary name, the library is actually much simpler than it sounds :) The main idea behind co-log is to treat logging actions as simple Haskell functions. Since functions are first-class citizens in Haskell and it is extremely easy to work with them.
