🌸 DESCRIPTION 🌸

Okay so picture this: a SelectSaver object is literally holding a reference to the file handle that was selected back when it got created. That's its whole thing. That's its moment. 💅

When its new method gets an extra parameter? Boom — that parameter is the one that gets selected. But if you don't hand it an extra parameter, then the currently selected file handle just... stays exactly as it was. No changes, no drama, we leave it alone fr fr. 🦋

And here's the glow-up moment: the second a SelectSaver gets destroyed, it re-selects the file handle that was selected when it was created. The way that it just... remembers for you. Iconic behavior honestly. 👑
