lenses for rust don't have to be an inference nightmare
// type-inferrable lenses for rust can exist
// the bokeh of a lens is the stuff that is out of focus.
// this trait describes how given the lens as context, and a bokeh
// you can reassemble the result.

You rolled out of bed and stretched your lazy bones and looked over at the clock. You're late to work.
Ever since western civilization figured out that necromancy was an easy path to a cheap labor force that didn't need to be fed, life, or rather unlife, has been going downhill. Fortunately, summoning rituals are too expensive, so the world isn't literally going to hell, yet.
You stumbled over to the bathroom shower, and shut the door. You don't have eyes any more, so there's no real point to turning on the lights. No real point to anything really. It's not like I have any other choice.
"Hey Suzy…" you hear from the bathroom door. "Are you in there?"
You groggily look around the room and look over at the door. There is no one in the bathroom.
