The liveness analysis uses the infinite nature of `loop`, and it was

I personally like `loop`. It reads nicely. It happens quite frequently
that I have a loop that works out best if I test the condition in the
middle, rather than the front or the end, or where the condition is
something quite involved; in such situations, `loop { ... }` is
perfect, and `while true { ... }` always feels second-class. I
recognize this is silly of me, though. :)
I also adore `loop` and rarely use `while`. I write code like this
constantly:
loop {
match port.recv() {
case DoSomething => { }
case Exit => break
}
}
