[Python-ideas] .then execution of actions following a future's completion

[Guido van Rossum]

I really don't want to distract Yury with this. Let's consider this (or
something that addresses the same need) for 3.8.

To be clear this is meant as a feature for concurrent.futures.Future, not
for asyncio.Future. (It's a bit confusing since you also change asyncio.)

Also to be honest I don't understand the use case *or* the semantics very
well. You have some explaining to do...
