       Returns an array holding the items of `arr' mapped through
       `ob->fun()'.   The  function  `fun'  in `ob' is called for
       each element in `arr' with that element  as  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.
