Can't load test-suite in ghci

[soenkehahn]

Because of missing language extension declarations (DataKinds, TypeOperators, etc.). You should either put them directly in the files or duplicate the ones from the cabal file in the .ghci file.

@soenkehahn I too am leaning towards bringing the extensions from the bookkeeper.cabal into individual files.

In the meantime, have you tried cabal new-repl or stack ghci instead of using plain ghci? I'm 99% sure both stack and cabal take care of running ghci in the context of the package.
