InstantiatedNamedWildcardsInConstraints.hs:4:14: error: [GHC-88464]
• Found type wildcard ‘_a’ standing for ‘b’
Where: ‘b’ is a rigid type variable bound by
the inferred type of foo :: (Enum b, Show b) => b -> (String, b)
at InstantiatedNamedWildcardsInConstraints.hs:4:1-40
To use the inferred type, enable PartialTypeSignatures
• In the type signature: foo :: (Enum _a, _) => _a -> (String, b)
