Distinction between `@isolated(any)` and `@_inheritActorContext`

I think this is related to how @_inheritActorContext interacts with isolated parameters. You might be interested in:

Closure isolation control

Greetings Swift evolvers. For your consideration, I have drafted a proposal allowing for more explicit control over the isolation of closures. You can read the proposal at nnnn-closure-isolation.md Please share thoughts and feedback here or as comments on the pull request. Thank you.

But for now, you can try explicitly capturing the isolated param value within the Task body like this:

return Task { [weak object] in
        _ = isolation // a capture affects the static isolation
        for try await element in stream {
            guard !Task.isCancelled,
                  let object
            else { return }

            try operation(object, element)
        }
    }
