Fix async-std at the price of breaking half the test suite - Don't mark impl trait as an error 2020-08-03 21:13:13 -04:00			`// check-pass`
Recurse into function bodies, but don't typeck closures Previously, rustdoc would issue a delay_span_bug ICE on the following code: ```rust pub fn a() -> impl Fn() -> u32 { \|\| content::doesnt::matter() } ``` This wasn't picked up earlier because having `type Alias = impl Trait;` in the same module caused _all closures_ to be typechecked, even if they wouldn't normally. Additionally, if _any_ error was emitted, no delay_span_bug would be emitted. So as part of this commit all of the tests were separated out into different files. 2020-07-09 09:13:59 -04:00			// manually desugared version of an `async fn` (but with a closure instead of a generator)
