I am one of the people who do not mind if it is not compatible.
As I said:
Trying to generate the exact same information as Delphi is IMHO not the right path.
If the RTTI unit is there, people who want Delphi compatibility can and should use that.
People with a more low-level mindset (such as me) will be able to work
around the low-level details.
