auto-reduced (treereduce-rust):

type Foo = impl Send;

struct A;

const VALUE: Foo = value();

fn test() {
    match VALUE {
        0 | 0 => {}

        _ => (),
    }
}

original:

#![feature(type_alias_impl_trait)]

type Foo = impl Send;

// This is not structural-match
struct A;

const fn value() -> Foo {
    A
}
const VALUE: Foo = value();

fn test() {
    match VALUE {
        0
            | 0 => {}
        //~^ `Foo` cannot be used in patterns
        _ => (),
    }
}

fn main() { self.f() }
