I would like to make a general comment that is likely not useful to the specific question asked (which I think has already been nicely answered by others). But I would like to point out this video of an excellent lecture on typeclasses given by Simon Peyton-Jones a few years ago. https://channel9.msdn.com/posts/MDCC-TechTalk-Classes-Jim-but-not-as-we-know...
