@deviant You ignore the resulting future (

Deferred

elizarov: I was actually just thinking about putting together a presentation for my team on exceptions and exception currying with coroutines. It seems to be an issue of much confusion in my team.

That is why I strongly recommend against using

unless you really need to do something concurrently. Unfortunately, for most people,

async

and futures is all they've heard about. Bad favor from other languages we have here.
