This is kind of a hack of case, though. I think what the OP was looking
for is
isPalindrome word
...
| (word == reverse word) = putStrLn (word ++ " is a palindrome")
  | otherwise              = putStrLn (word ++ " is not a palindrome")
Erm?  It's as much of a hack of case as yours is, since the above is
actually using case.
