Hey David, great to find you here!!
I really like what you're proposing. I could make it a generator instead of
returning a list. I returned a list because wait returns sets and I thought I
would keep returning collections. I'll play around and send a new proposal.

Hello list, it's my first email here, so let me know if this is in any way out
of order.
I've been working a lot with concurrent.futures lately. I find both `wait` and
`as_completed` very useful, but something I'm usually lacking is a `wait`
version where the order of the futures is preserved.
