Macro zip 

macro_rules! zip {
    ($($es:expr),+ $(,)?) => { ... };
    (@flatten; $($prev:expr,)*; $tuple:expr; $e:expr) => { ... };
    (@flatten; $($prev:expr,)*; $tuple:expr; $e:expr, $($es:expr),+) => { ... };
}

Zips arbitrarily many futures, waiting for all to complete.

Examples

use futures_micro::zip;

let a = async { 1 };
let b = async { 2 };

assert_eq!(zip!(a, b).await, (1, 2));
