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.
