I guess you are replying to me.  Perhaps it would be best not to cut
everything in the reply.

No, I know exactly what Array#uniq! does:
------------------------------------------------------------ Array#uniq!
     array.uniq! -> array or nil
------------------------------------------------------------------------
     Removes duplicate elements from self. Returns nil if no changes
     are made (that is, no duplicates are found).

        a = [ "a", "a", "b", "b", "c" ]
        a.uniq!   #=> ["a", "b", "c"]
        b = [ "a", "b", "c" ]
        b.uniq!   #=> nil

As I said I wasn't sure what you were trying to accomplish and what object
should eliminate duplicates.

If you think about my example a bit, I suspect you'll be able to suss it
out.
