Can't build with GHC 8.8.4 #31

Which version was this tested with? I tried building version 0.0.1 on GHC 8.8.4 and I got this error:

[ 3 of 23] Compiling Data.Profunctor.Optic.Index ( src/Data/Profunctor/Optic/Index.hs, dist/build/Data/Profunctor/Optic/Index.o )

src/Data/Profunctor/Optic/Index.hs:151:10: error:
    • The type synonym ‘Cx'’ should have 3 arguments, but has been given 1

cabal: Failed to build profunctor-optics-0.0.1

Thanks for your patience, it looks like exactly what I was looking for!

Sorry for the late reply: 0.0.1 was written with GHC 8.6.3.

Probably obvious, but this library is not exactly stable :). I wouldn't recommend depending on it for anything too serious.
