Figure out if there is a way to remove duplicate / boiler plate in our code. TemplateHaskell?

[Martinsos]

There is a lot of duplication inside the code of the strong-path library because we have 12 different constructors we are dealing with. I am pretty sure we can remove some of that duplication using TemplateHaskell, so we could try that. Maybe there is an even more elegant way though? Worth researching.
