Use check-pass in ui tests where appropriate 2019-11-04 00:00:00 +00:00			`//@ check-pass`
Refactor async fn return type lowering async fn now lowers directly to an existential type declaration rather than reusing the `impl Trait` return type lowering. As part of this, it lowers all argument-position elided lifetimes using the in-band-lifetimes machinery, creating fresh parameter names for each of them, using each lifetime parameter as a generic argument to the generated existential type. This doesn't currently successfully allow multiple argument-position elided lifetimes since `existential type` doesn't yet support multiple lifetimes where neither outlive the other. This requires a separate fix. 2019-03-13 17:42:23 -07:00			`//@ edition:2018`
