        mixed *turn_array(mixed *arr);
          turns the contents of the array (changes it indeed!) and returns
          it:
          int *a;
          a = ({ 1,2,3,4 });
          b = turn_array(a);
          return ({ a,b });
          ==> ({ ({ 4,3,2,1 }),({ 4,3,2,1 }) })

          If you want to keep the old array unchanged, use [0..] to copy
          the array before you give it to turn_array():
          a = ({ 1,2,3,4 });
          b = turn_array(a[0..]);
          return ({ a,b });
          ==> ({ ({ 1,2,3,4 }),({ 4,3,2,1 }) })

Works also on strings.
