Support for older GHC versions

[jonkri]

I'm looking to analyze package APIs over time (for background, see haskell/pvp#63). Ideally, I would like to extract the APIs of all versions of all Hackage packages.

Do we know what challenges there would be when it comes to backporting print-api to older GHC versions?

I do not know if there are any real challenges. You just have to follow the directory structure and adapt the calls to the GHC API. This shouldn't be too hard, it's just grunt work. :)
