tcfail201.hs:17:58: error:
• Couldn't match expected type ‘a’ with actual type ‘HsDoc id0’
‘a’ is a rigid type variable bound by
the type signature for:
gfoldl' :: forall (c :: * -> *) a.
(forall a1 b. c (a1 -> b) -> a1 -> c b)
-> (forall g. g -> c g) -> a -> c a
at tcfail201.hs:15:12
• In the first argument of ‘z’, namely ‘DocEmpty’
In the expression: z DocEmpty
• Relevant bindings include
hsDoc :: a (bound at tcfail201.hs:16:13)
gfoldl' :: (forall a1 b. c (a1 -> b) -> a1 -> c b)
-> (forall g. g -> c g) -> a -> c a
