Yeah, I think I understand why you had to write it this way, but the fact that this lifetime needs to be bubbled up so far up is really non-intuitive to me.

Me, too. :) I find myself limited by my way of thinking here, coming from C++ ("I _know_ it lives long enough, why don't you let me express this?").
Agreed, it _is_ annoying. It bubbles up everywhere and it feels like "something to silence the compiler" more than "something to express the safety of the code", as other people have pointed out.
