Set::Scalar::Universe — universes for set members 🪐

🌸 SYNOPSIS 🌸

Do not use directly.

not me telling you to NOT use something in the synopsis 💀 fr fr, this is not the module you call up on a Friday night. It's an internal bestie.

🎀 DESCRIPTION 🎀

There are only two guaranteed interfaces here, and honestly? both of them are sort of indirect. lowkey shy. highkey useful. 🙈

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. ✨ so like, you ask the set for its universe, then you ask that universe for its members, and boom, that's the crew.

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: (). 💅

so if you ever see [] you're looking at a universe, and if you see () you're looking at a plain old set. that's the whole visual difference check. no cap. 👑
