T11010.hs:9:34: error:
• Couldn't match type ‘a1’ with ‘Int’
Expected: a -> b
Actual: a1 -> b
‘a1’ is a rigid type variable bound by
a pattern with constructor:
Fun :: forall a b. String -> (a -> b) -> Expr a -> Expr b,
in a pattern synonym declaration
at T11010.hs:9:26-36
• In the declaration for pattern synonym ‘IntFun’
• Relevant bindings include
x :: Expr a1 (bound at T11010.hs:9:36)
f :: a1 -> b (bound at T11010.hs:9:34)
