Once again I think this is not useful so it can be disregarded.

I wanted to learn how I could call Free on class fields (like management operators call Finalize on records) but it’s more complicated than I thought (again). Records with management operators hook into the RTTI system it looks like, but how does a record with management operators get added to the classes RTTI information? I mean in TObject.CleanupInstance there is a vInitTable which gets set if the record has management operators in them but I can’t find where.
