The `bugprone-no-escape` check seems to be a bit limited because it only works with `dispatch_async` and `dispatch_after` (from Apple, it seems). It could probably be expanded to include some more async constructs, but adding support for other variable types looks like it would be a positive that would immediately work for the above functions. Only the diagnostic of the check would need to be adjusted a bit.
