works kinda well, but doesn't complain about unknown config values in
json, which is kinda hmpf tbh

(this is commented out in the cabal file, since unfortunately the
servant-js package is broken in nixpkgs and therefore otherwise breaks
the nix build process … but it can be used "by hand")

(and they can be useful, too!)

Also, documentation & deleting imports / extensions that aren't used.

(at least for a few simple things)

Also, more modules!

lots of lenses in this stuff :(

unfortunately doesn't quite get rid of all the type family still
since it's just too useful … but does reduce it somewhat.

Also, maps are much easier for looking things up than vectors!
