Rollup merge of #50656 - leodasvacas:fix-impl-trait-in-main-ret, r=nikomatsakis
Fix `fn main() -> impl Trait` for non-`Termination` trait Fixes #50595. This bug currently affects stable. Why I think we can go for hard error: - It will in stable for at most one cycle and there is no legitimate reason to abuse it, nor any known uses in the wild. - It only affects `bin` crates (which have a `main`), so there is little practical difference between a hard error or a deny lint, both are a one line fix. The fix was to just unshadow a variable. Thanks @nikomatsakis for the mentoring! r? @nikomatsakis
