#### experimental::awaitable_operators::operator && (4 of 6 overloads)

Wait for both operations to succeed.

    template<
        typename T,
        typename U,
        typename Executor>
    awaitable< std::tuple< T, U >, Executor > operator &&(
        awaitable< T, Executor > t,
        awaitable< U, Executor > u);

If one operations fails, the other is cancelled as the AND-condition can no longer be satisfied.
