[jacklberk]

In tests/src/task.rs1

#[macro_export]
macro_rules! matches_override {
    ($expression:expr, $($pattern:tt)+) => {
        match $expression {
            $($pattern)+ => true,
            _ => false
        }
    }
}

Should be replaced with default match macro https://doc.rust-lang.org/beta/std/macro.matches.html
