T9036.hs:18:17: error:
• Couldn't match type ‘Curried t0 [t0]’ with ‘Curried t [t]’
Expected type: Maybe (GetMonad t after) -> Curried t [t]
Actual type: Maybe (GetMonad t0 after) -> Curried t0 [t0]
NB: ‘Curried’ is a non-injective type family
The type variable ‘t0’ is ambiguous
• In the ambiguity check for ‘simpleLogger’
To defer the ambiguity check to use sites, enable AllowAmbiguousTypes
In the type signature:
simpleLogger :: Maybe (GetMonad t after) -> t `Curried` [t]
