You are trying to something slightly complex. I don't see how one could make it any easier from a language design perspective and staying idiomatic to the language.
Go: Goroutines make you wire the "stop" scenario on your own (channel close).
Rust: Hold on to your future and drop() it.
C#: Pass a cancellation token and call Cancel()
All seem reasonable and stay within what they think their developers will be able to pick up and run with.
