Couldn't match type ‘Curried t [t]’ with ‘Curried t0 [t0]’
NB: ‘Curried’ is a type function, and may not be injective
The type variable ‘t0’ is ambiguous
Expected type: Maybe (GetMonad t after) -> Curried t [t]
Actual type: Maybe (GetMonad t0 after) -> Curried t0 [t0]
In the ambiguity check for:
forall t after. Maybe (GetMonad t after) -> Curried t [t]
To defer the ambiguity check to use sites, enable AllowAmbiguousTypes
In the type signature for ‘simpleLogger’:
simpleLogger :: Maybe (GetMonad t after) -> t `Curried` [t]
