proptest! macro triggers clippy::unnecessary_operation

[Byter09]

Hello.

The following test triggers clippy::unnecessary_operation...

proptest! {
    #[test]
    fn proptest_sizeof_multiple_of_alignof(t in arb_type()) {
        if let Ok(sizeof) = t.sizeof() {
            prop_assert_eq!(sizeof % t.alignof().unwrap(), 0);
        }
    }
}

... probably because the expansion ends up with this:

match runner.run( 
    ...
) {
    Ok(_) => (),
    Err(e) => panic!(),
}

If there's a better way to express/rewrite the test, I'd prefer that of course.
Otherwise I hope it's not causing too much trouble by kindly requesting #[allow(clippy::unnecessary_operation)] to be added.

Thank you.

FYI this might be better addressed upstream.

Clippy is in the middle of trying to work out which lints should/shouldn't trigger for external macros: rust-clippy#4949, rust-clippy#5362. They've been receptive when requesting similar things for other lints.
