Hm, interesting.

We would need to change it all over the place, though.

Underscore has been used and means something in butter for a long time. I don't even remember when we picked that up. The number of underscores means how many scopes up it lives, but two underscores is pretty rare. I would enforce it if I see it in a review, though.

I'm down with challenges to this system, but I would push to have that in another ticket.
