       mixed unique_array( object *obarr, string separator,  void
       | mixed skip );

DDEESSCCRRIIPPTTIIOONN
       Groups objects together for which the `separator' function
       returns the same value. `obarr'  should  be  an  array  of
       objects,  other  types are ignored.  The `separator' func-
       tion is called only once in each object in  `obarr'.   THe
       optional `skip' parameter enables a pre-filter on `obarr',
       skipping elements which match `skip'.

            ({
                ({Same1:1, Same1:2, Same1:3, .... Same1:N }),
                ({Same2:1, Same2:2, Same2:3, .... Same2:N }),
                ({Same3:1, Same3:2, Same3:3, .... Same3:N }),
                              ....
                ({SameM:1, SameM:2, SameM:3, .... SameM:N }),
            })
