Hlinting

[jrp2014]

Thanks for the book. I wish that I had bought it sooner. It is one of the few programming / haskell books that explains some of the mysteries in a lucid way, while offering insights into the tradeoffs into between the different idioms.

Here's a modicum of hlint refactoring.

The main issue that the software has is that it should move to using the Network.Socket library as the existing network library code is deprecated. An exercise for another day.

Happy to revert the changes that you have identified above.

The next task will be to update the networking; a good few usages seem to be deprecated with the recommendation to use Network.Socket instead of Network. I assume that this is to provide a more general API, but can't find any documentation on how to do the update systematically.
