Adding a Promise library?

This might be helpful for composing async tasks.

Might be interesting indeed! If you wish to contribute it feel free :)

Good to know!

Also, I think it might be helpful if async API could also return a Promise like React Native did (and still support callback/block API)

Location.geocode('apple inc').then do |location|
  puts location.address
end.rescue |error|
  puts error
end

Indeed, we could change the existing APIs to return a Promise instead. But I guess we need to figure out the initial API and implementation first.
