          map_array() - modify an array of elements via application of
          a function

          mixed *map_array( mixed *arr, string fun, object ob,
                            mixed extra, ... );
          mixed *map_array( mixed *arr, function f, mixed extra, ... );

          Returns an array holding the items of `arr' mapped through
          either `ob->fun()' or 'f'.  The function is called for each
          element in 'arr' with that element as a parameter. A second
          parameter `extra' is sent in each call if given.  Principal
          function:

               foreach (index) arr[index] = ob->fun(arr[index],extra);

          The value returned by `ob->fun(arr[.index.], extra)' replaces the existing
          element in the array. If `arr' is not an array, then 0 will be returned.
