> could be async IO and require being called in the context of an async runtime
The compiler already has knowledge that a function is being called as async - what prevents it from ensuring that a runtime is present when it does?
> blocking synchronously on an async task in an async runtime can result in deadlocks from task waiting on runtime IO polling but the waiting preventing the runtime from being polled

What prevents the runtime from preempting a task?
