annfail08.hs:9:1:
No instance for (Data.Data.Data (a0 -> a0))
arising from an annotation
The type variable `a0' is ambiguous
Possible fix: add a type signature that fixes these type variable(s)
Possible fix:
add an instance declaration for (Data.Data.Data (a0 -> a0))
In the expression: (id + 1)
In the annotation: {-# ANN f (id + 1) #-}
