error[E0700]: hidden type for `impl Trait<'a, 'b>` captures lifetime that does not appear in bounds
--> $DIR/ordinary-bounds-unsuited.rs:31:33

LL | fn upper_bounds<'a, 'b>(a: Ordinary<'a>, b: Ordinary<'b>) -> impl Trait<'a, 'b>
| -- hidden type `Ordinary<'b>` captures the lifetime `'b` as defined here
...
LL | if condition() { a } else { b }

help: to declare that the `impl Trait` captures `'b`, you can add an explicit `'b` lifetime bound

LL | fn upper_bounds<'a, 'b>(a: Ordinary<'a>, b: Ordinary<'b>) -> impl Trait<'a, 'b> + 'b
