TH_localname.hs:3:11: error:
• Ambiguous type variable ‘t0’ arising from a use of ‘Language.Haskell.TH.Syntax.lift’
prevents the constraint ‘(Language.Haskell.TH.Syntax.Lift
t0)’ from being solved.
Relevant bindings include
y :: t0 (bound at TH_localname.hs:3:6)
x :: t0 -> m0 Language.Haskell.TH.Syntax.Exp
(bound at TH_localname.hs:3:1)
Probable fix: use a type annotation to specify what ‘t0’ should be.
Potentially matching instances:
instance (Language.Haskell.TH.Syntax.Lift a,
Language.Haskell.TH.Syntax.Lift b) =>
Language.Haskell.TH.Syntax.Lift (Either a b)

instance Language.Haskell.TH.Syntax.Lift a =>
Language.Haskell.TH.Syntax.Lift (Maybe a)
-- Defined in ‘Language.Haskell.TH.Syntax’
...plus 15 others
