// Due to a compiler bug, if a return occurs outside of a function body
// (e.g. in an AnonConst body), the return value expression would not be
// type-checked, leading to an ICE. This test checks that the ICE no
// longer happens, and that an appropriate error message is issued that
// also explains why the return is considered "outside of a function body"
// if it seems to be inside one, as in the main function below.
const C: [(); 42] = {
[(); return || {
//~^ ERROR: return statement outside of function body [E0572]
let tx;
}]
};
struct S {}
trait Tr {
fn foo();
fn bar() {
//~^ NOTE: ...not the enclosing function body
[(); return];
//~^ ERROR: return statement outside of function body [E0572]
//~| NOTE: the return is part of this body...
}
