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: ().
