Can FPC have default class properties in Delphi mode or even ObjFpc mode?


i probably won't really do it, for my major concern is still Delphi, and  
that makes a special note that "defaul" and "class" are mutually exclusive.

  Pity... i wished to do a light-weight factory (which Delphi class  
references are to an extent). I would have to resort to global procedure,  
but that is less elegant.
  And calling TClassName.a(DataPayload) is awful. TClassName[DataPayload]  
would be neat...
