Description

I saw some discussion about askUnordered by @ktoso and @patriknw in #24325. Is there still some prospect to add to streams API or is this ruled out? I'd be happy to make a PR.

I have a (perhaps unusual) use-case where I specifically want my actor to process messages out-of-order. Its mailbox implements a first-in-random-out queue. This is for a Monte Carlo scheme.

Thanks in advance.
