To the extent that it will affect ONLY my opinion of the language I reserve judgement, but prima facie, I'm a little worried that this will prove to be a distraction.

If the language didn't have a std implementation of async/await, would it affect your decision to use Xig? Or are you comfortable with traditional multithreaded facilities to the extent that you require concurrency (and parallelism)?
