Such new Delphi features are only enabled by default in FPC modes if  
we consider them to not run counter to the spirit of Pascal. That's  
obviously subjective, but so is Embarcadero's decision to introduce  
them. There will never be convergence, because Embarcadero is not  
interested in that.

You can use {$modeswitch advancedrecords} to enable them in any  
non-Delphi syntax mode  
(http://www.freepascal.org/docs-html/prog/progsu106.html ). Virtually  
all new language features we add these days can be selectively enabled  
and disabled via mode switches.
