SYNOPSISDo not use directly.
DESCRIPTIONThere are only two guaranteed interfaces, both sort of indirect.
The first one is accessing the universe of a set:
This contains the members of the universe
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: ().
