I'm not sure if it's a good idea. Perl is adjusting the slots to each other depending on use history.
Hence you'd magically loose information, and I'm not aware of a way to inhibit this.
That's awfully hard to debug if it happens.
(will add an example later)
updatePlaying around, look at what happens at line 7
after incrementing $v, i.e. changing it in numeric context, the string-slot is adjusted to the number-slot°
So can this only happen when I change one of the slots?
If yes, shouldn't such dualvars always been made readonly, too?
Hope you understand my worries.

FWIW: a very good article from Brian here: https://www.effectiveperlprogramming.com/2011/12/create-your-own-dualvars/
