@steveklabnik ran into this error; what do I Google to figure out what I'm doing wrong and how to fix it? https://gist.github.com/shepmaster/9ec942bb74838a070781 …
@steveklabnik I'm missing why unsafe. Is it because it can't see that the reference isn't saved/used after the fn returns?

@JakeGoulding yes, it can't tell if you've ACTUALLY mutated the thing, just that you're trying to borrow mutably twice at the same time -
@steveklabnik What I'm missing is why is the first borrow live after the function returns? I'm guessing that I *could* have saved it.
