No instance for (Show (v (v a)))
arising from the 'deriving' clause of a data type declaration at drvfail003.hs:13:5
Possible fix: add an instance declaration for (Show (v (v a)))
When deriving the `Show' instance for type `Square_'
Variable occurs more often in a constraint than in the instance head
in the constraint: Show (v (v a))
(Use -fallow-undecidable-instances to permit this)
In the derived instance
instance (Show (v (v a))) => Show (Square_ v w a)
