As far as I can tell, with this async approach you lose what I consider to be one of the main benefits of the native async functions; If an error is thrown, it will show up in the "reject" path of your promise. This is very useful and is great at preventing "random code" in some Task from causing havoc. I'm not that great at functional programming, and perhaps this is a non-issue, but I feel there could be some way to achieve the same results without losing that ability.
