Macro futures_micro::zips

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

Like ors, but combines with zip instead of or, only returning when all are completed.
