module Test where
data R = R {f :: Int}
foo:: (?x :: Int) => R -> R
foo r = r {f = ?x}
Test.hs:4:
Could not deduce `?x :: Int' from the context ()
Probable fix:
Add `?x :: Int' to the the type signature of an expression
arising from use of implicit parameter `?x' at Test.hs:4
In the record update: r {f = ?x}
In the definition of `foo': r {f = ?x}
