rustc: rework stability to be on-demand for type-directed lookup. 2016-11-10 19:08:21 +02:00			`#![feature(fn_traits)]`

Stabilize rvalue promotion to 'static. 2017-08-13 11:46:49 +03:00			`fn id<T>(x: T) -> T { x }`

Update test files; mostly the problem is that they were using the explicit form `Fn<A,B>` and now should use `Fn(A) -> B` or `Fn<A,Output=B>`, but in some cases we get duplicate error reports. This is mildly annoying and arises because of the main error and another error from the projection. Might be worth squashing those, but seems like a separate problem. 2015-01-12 10:27:25 -05:00			`pub fn foo<'a, F: Fn(&'a ())>(bar: F) {`
