Ahh, of course! Without the changes from [Closure isolation control](https://forums.swift.org/t/closure-isolation-control/70378), I have to be really careful about how isolation is inherited within that `Task`.

Here's the solution:

```swift
	func notOk(isolation: isolated (any Actor)? = #isolation) {
		let op = {
			print(self.value)
		}

		Task {
			_ = isolation // this is critical to get the correct inheritance
			op()
		}
	}

```
