What I particularly like is that you considered it as a bug and were 
open for a discussion from the very beginning - even if the behavior was 
Delphi compatible at that point. Not like Embarcadero closing eyes and 
ears until they really had to solve it. All kudos to you and the FPC team :)

Maybe Embarcadero changes their record inheritance policy as well at 
some point - especially because they introduced record helpers for 
primitive types (like TStringHelper). Not having inheritance for them 
forbids easy extension of them.
