Potentially missing imports?

[chrissound]

Thanks for the tutorial first of all!

I'm following through with the tutorial and at this line: https://github.com/vacationlabs/haskell-webapps/blame/master/doc/docs/opaleye/basic-db-mapping.rst#L108

we have $(makeAdaptorAndInstance "pTenant" ''TenantPoly) however makeAdaptorAndInstance does not appear to be imported.

Is this from Data.Profunctor.Product.TH?

I'm guessing we also need:

{-# LANGUAGE FlexibleInstances #-}
{-# LANGUAGE MultiParamTypeClasses #-}

hlint starterApp/Main.hs complians about missing of MultiParamTypeClasses
