EXPORTS
   *   is_palindrome

FUNCTIONS
 is_palindrome
   Returns true if the string, array, or array_ref is a palindrome. If more
   than one parameter is passed to the function, then it will blindly
   assume that you want to treat them as an array to be tested. This means
   that you could, theoretically, pass in a palindrome of array_refs and it
   would still pass.

   If only one arg is passed, then it is first checked to see if it is an
   array ref. If it is an array ref it is treated as a normal array. If it
   is a simple scalar, then it is treated as a string. If it is any other
   type of ref, then undef is returned. Additionally, a blank array ref
   also returns undef.
