Hello, This code runs ok http://lpaste.net/91814 but only thanks to enforcing [()] on line 12. In GHCI *Main> :t (List []) (List []) :: NestedList a and *Main> :t flatten (List []) flatten (List []) :: [a] That means ghc cannot infer the type. Is there a way how to # print flatten (List []) ? Or even more general, print [] without enforcing the type? Thank you Lukas
