Hello, I was experimenting with TypeInType and run into a problem, that can be reduced to the following example. Does anyone have any insight on what causes the error, in particular why is `IxKind` not being reduced? -Iavor {-# Language TypeInType, TypeFamilies #-} module Help where import Data.Kind type family IxKind (m :: Type) :: Type type family Value (m :: Type) :: IxKind m -> Type data T (k :: Type) (f :: k -> Type) type instance IxKind (T k f) = k type instance Value (T k f) = f {- [1 of 1] Compiling Help ( Desktop/Help.hs, interpreted ) Desktop/Help.hs:13:31: error: • Expected kind ‘IxKind (T k f) -> *’, but ‘f’ has kind ‘k -> *’ • In the type ‘f’ In the type instance declaration for ‘Value’ | 13 | type instance Value (T k f) = f | ^ Failed, no modules loaded. -}
