NAME
Set::Scalar::Universe - universes for set members
SYNOPSIS
Do not use directly.
DESCRIPTION
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: ().
