+drvfail007.hs:4:38:
+ No instance for (Eq (Int -> Int))
+ arising from the 'deriving' clause of a data type declaration
+ Possible fix:
+ add an instance declaration for (Eq (Int -> Int))
+ or use a standalone 'deriving instance' declaration,
+ so you can specify the instance context yourself
+ When deriving the instance for (Eq Foo)
