I'm much more lukewarm on set_state(). How hard is it to reimplement
one's own Future if someone wants a different implementation? By
allowing people to change the future's internal state, we're also
giving them a (small) gun to shoot themselves with.

No strong opinion on this, but it sounds ok. That means
`future.state()` would return an enum value, not a bare string?
