This causes an error, because numeric literals like 2 are polymorphic: > :t 2 2 :: Num a => a If you fix the type to Integer, it works as expected: insert (2 :: Integer) [9,2] By the way: It's helpful to include the error messages in your mail when some piece of code doesn't compile. Cheers, Daniel
