#![allow(unused)]

trait StageTrait {
    type Fallback: StageTrait;

    fn run<G: StageFinder<Target = Self>>(head: &mut G::Head) {
        StageTrait::run::<FindFallback<G>>(head);
    }
}

struct FindHead<H>(H);

    type Target = H;
}

struct FindFallback<G>(G);

}

struct Loop;
impl StageTrait for Loop {
    type Fallback = Loop;
}

struct MyStage<T: StageTrait>(T);

impl<T: StageTrait> StageTrait for MyStage<T> {
    type Fallback = T;

    fn run<G: StageFinder<Target = Self>>(head: &mut G::Head) {
        StageTrait::run::<FindFallback<G>>(head);
    }
}

fn main() {
    StageTrait::run::<FindHead<_>>(&mut MyStage(Loop));
}

My second issue of the day unfortunately (#143097).
