Description
I'm getting a ton of Kind errors on standalone deriving via instances:
For example:
src/Data/Functor/Monoidal.hs:725:59: error:
• Couldn't match kind ‘k’ with ‘*’
Expected kind ‘* -> *’, but ‘f’ has kind ‘k -> *’
‘k’ is a rigid type variable bound by
the deriving clause for ‘FromDecidable (Reverse f)’
at src/Data/Functor/Monoidal.hs:725:14-38
deriving via FromDecidable (Reverse f) instance Decidable f => Monoidal (->) Either Void (,) () (Reverse f)
I'm enabling all the same pragmas for doctest
as I enable in my cabal file for the main build.
This is GHC 9.4.8
and doctest 0.22.2
.
