Sven, When you have the time could you look at issue #22019 titled "Cannot return generic derived class"? I think it's kind of a big issue because it prevents anyone from returning a subclass of a generic type. I just want to know that's you've read the bug report and see/understand the issue.
In a nutshell you currently cannot write something like: function TList<T>.GetEnumerator: TEnumerator<T>; begin // TListEnumerator<T> inherits from TEnumerator<T> return TListEnumerator<T>.Create(Self); end; There are other examples, but I think the above and the details provided in the bug report should be enough to convey the problem. Thanks Sven! We all very much appreciate your work!
