in thread Find unique elements from multiple arrays

Perhaps a solution would be to use the values instead of the keys, but this means that all the data is copied about again, and so is highly unlikely to be the most efficient approach.

my @new = do{local %h; @h{@a,@b,@c,@d} = (@a,@b,@c,@d); values %h};

    That doesn't solve the problem at all. It fails for exactly the same reason:
    $ perl -le '@a = (undef, ""); @u = do {@h {@a} = @a; values %h}; print + scalar @u' 1 $
