It sounds like the @ character is serving two different purposes which confused
me at first.
If I understood correctly, you are using it to get the key path but also to
apply the key path to the bag struct and get the corresponding value.
Yes. And the initial proposal suggest the following syntax accordingly:
let path = Bag.things[0].name
bag[path]
bag[.things[0].name]
bag[Bag.things[0].name]
bag.things[0][.name]
bag.things[0][Thing.name]
