A yield expression was used outside of the coroutine literal.
Erroneous code example:
```compile_fail,E0627
#![feature(coroutines, coroutine_trait)]
fn fake_coroutine() -> &'static str {
yield 1;
return "foo"
}
fn main() {
let mut coroutine = fake_coroutine;
}
```
The error occurs because keyword `yield` can only be used inside the coroutine
literal. This can be fixed by constructing the coroutine correctly.
```
#![feature(coroutines, coroutine_trait)]
fn main() {
let mut coroutine = || {
yield 1;
return "foo"
};
}
```
