[1 of 2] Compiling Util ( Util.hs, dist/build/Util.o )
Util.hs:136:28: error:
• Could not deduce (Semigroup b) arising from a use of ‘<>’
from the context: (Applicative p, Monoid b, Foldable f)
bound by the type signature for:
foldMapA :: forall (p :: * -> *) b (f :: * -> *) a.
(Applicative p, Monoid b, Foldable f) =>
(a -> p b) -> f a -> p b
at Util.hs:135:1-77
Possible fix:
add (Semigroup b) to the context of
the type signature for:
foldMapA :: forall (p :: * -> *) b (f :: * -> *) a.
(Applicative p, Monoid b, Foldable f) =>
(a -> p b) -> f a -> p b
• In the first argument of ‘liftA2’, namely ‘(<>)’
In the first argument of ‘(.)’, namely ‘liftA2 (<>)’
In the first argument of ‘foldr’, namely ‘(liftA2 (<>) . f)’
