revamp how we handle elision in async fn We now always make fresh lifetimne parameters for all elided lifetimes, whether they are in the inputs or outputs. But then we generate `'_` in the case of elided lifetimes from the outputs. Example: ```rust async fn foo<'a>(x: &'a u32) -> &u32 { .. } ``` becomes ```rust type Foo<'a, 'b> = impl Future<Output = &'b u32>; fn foo<'a>(x: &'a u32) -> Foo<'a, '_> ``` 2019-08-12 21:15:33 +00:00			`// edition:2018`
