       What should GHCi do?  Strictly speaking, the program is ambiguous.  <literal>show (reverse [])</literal>

   ""
-  ghci> (reverse []) :: [Int]
+  ghci> reverse ([] :: [Int])
   []

     However, it is tiresome for the user to have to specify the type, so GHCi extends Haskell's type-defaulting
