Set::Scalar::Universe - universes for set members

Do not use directly.

There are only two guaranteed interfaces, both sort of indirect.

The first one is accessing the universe of a set:

    $set->universe

This contains the members of the universe

    $set->universe->members

of the $set.

The second supported interface is displaying set universes.

    print $set->universe, "\n";

This will display the members of the set inside square brackets: [], as opposed to sets, which have their members shown inside parentheses: ().
