Let's say you are within a suspend function... What's the most pragmatic way to cancel your execution? Should you just throw a cancellation exception? Or maybe somehow grab the current job and cancel that?

My use case: I have a third party "cancellation token" i want to check within a suspend function to see if cancellation has been requested. If so, i want to just cancel current suspend function

To cancel the current coroutine, throw an exception. If you just cancel the job, then your coroutine will continue to execute until something suspends or checks the job status. 

<@U0KMMQA20> yeah my plan was to do both. Cancel current job and then throw cancellation exception

Just throwing the exception should be enough. Otherwise the job will logically have two cancellation exceptions, which is confusing.
