I also just noticed that your example uses:
zip(PRIMES, executor.map(is_prime, PRIMES))
But your doc explicitly says:
map(func, *iterables, timeout=None)
Equivalent to map(func, *iterables) but executed asynchronously and
possibly out-of-order.
So it isn't safe to zip() against something that can return out of order.
Which opens up a discussion about how these things should be used.
Given that your other example uses a dict to get back to the original
arguments, and this example uses zip() [incorrectly], it seems that the
Futures object should have the arguments easily accessible. It certainly
seems like a common use case that if things are going to be returned in
arbitrary order, you'll want an easy way to distinguish which one you
have. Having to write a dict map before each call can be done, but
seems unoptimal.
