Let's assume I have an GUI application and I want to record some user-actions which can be replayed.

And this replay should be possible even if the application layout changes. Hence, I somehow need to identify the run-time objects in a way that this identification stays the same while the app is further developed and between user sessions.

And I don't want to manually manage all IDs (initially) but use the compiler for this.

Is there any way to generate such stable unique IDs at compile-time? I can imagine that his maybe needs to be combined with a mixin that is used inside a constructor to get IDs into run-time objects.

The compiler needs something to go off of that isn't going to change between revisions. Maybe the fully qualified name? Then you can hash that.
