Yep, that comes for free from the model. Though, if you're asking if we can have two unique references (like `&mut`) to two different entries, not yet. Nick's original proposal had some thoughts on how we can do that, and Zeta (another language implementing group borrowing) has some neat dependent-type-ish mechanisms for that. I'm still considering what Valen will want to do there.
