Hi guys,

Maybe a stupid question, I try to create a cancellation scope in Kotlin and I cannot ged rid of the error:

> Overload resolution ambiguity. All these functions match.  
> public open fun newCancellationScope(proc: Functions.Proc1\<CancellationScope!\>!): CancellationScope! defined in io.temporal.workflow.Workflow  
> public open fun newCancellationScope(runnable: Runnable!): CancellationScope! defined in io.temporal.workflow.Workflow\> Blockquote

So, how can I create a CancellationScope in Kotlin? Do you have any examples how to create it?

You could create a Runnable and pass it as param to Workflow.newCancellationScope, for example:

```auto
val runnable = Runnable {
  Async.function(activity::execActivity)
  // ...
}

val c = Workflow.newCancellationScope(runnable)
c.run()
// ...

```
