How do I wait_any for two things of different type in a loop?

Question

How can I wait for two or more things (with different types) at the same time? Like in an event loop:

while(true) {
    ppl::task<Letter> msg1 = WaitForLetter(); //one letter a month
    ppl::task<SMS> msg2 = WaitForSMS(); //one SMS an hour

    //wait_any. How to do it for tasks of different types?
}

I'll answer my own post.

"PPL Power Pack" supports "Heterogeneous when_any":

On an unrelated note it seems very few people use PPL. There are only 97 PPL tagged questions on stackoverflow. Most have no answers. (TBB has 450, so it seems a slightly more active community)
