Can define and use async fn without feature gate on nightly #60069
Description
#![feature(futures_api)]
pub struct Foo;
impl Foo {
pub async fn foo(&mut self) {
}
}
fn main() {
let mut bar = Foo;
bar.foo();
}(playground) runs without error, for some reason the async_await feature gate is not required.

@Nemo157 Just to be clear: Is there a way to access
async fnwith no feature gate at all? The provided example is at least opting into#![feature(futures_api)].If one must use some feature gate to use
async fn, then I'd be tempted to prioritize this as P-medium, not P-high.pnkfelix commentedon Apr 18, 2019
(leaving nominated and unprioritized for now, at least until above question is resolved.)

triage: Based on @eddyb's statement that our plan is to stabilize futures "soon", I'll assign this P-high priority for now. Leaving nominated due to the question I posted above.

@pnkfelix not that I could find, but
futures_apiis currently in FCP for stabilization.varkor commentedon Apr 18, 2019
