Why? How is

        @main_list = ....;
        @more_stuf = ....;

        @just_to_do_a_job{@main_list} = ();
        @just_to_do_a_job{@more_stuff} = ();

        @main_list = keys %just_to_do_a_job;

more or less efficient than

        @main_list union= @more_stuff;

Both have to go through the same amount of work ("work is conserved")
but one is more efficient in terms of the user's brainpower.
