So the question is, why do you want to abstract them away into decorator-list, instead of for example creating a "PythonDeclaration" which has a "bool isAbstractMethod()"? (of course only for the decorators/attributes which are interesting to you)

Okay, I see your point.
No, decorators are not like attribute keywords, because there's no fixed set of decorators. It's only a syntax for calling a function, if you want to put it like that. Many frameworks (like SQLAlchemy, Django, ...) introduce decorators to modify methods and classes, and it would be useful to track that. As the set of decorators can change at any time (you can even define your own ones) this can not be solved by adding some enum flags to a declaration. See my previous post for a simple custom example.

If I want to put this into python only, I'll need to subclass Declaration and add an appended list to it. However, Declaration already defines appended lists. What's the syntax for adding another one? I couldn't find any example for that, and I didn't manage to do it by myself, either.

Thanks,
Sven
