[fpc-devel] Observer support in Delphi

[luiz americo pereira camara]

While looking for the new TextHint property in Delphi docs, i found that
recent Delphi implements Observer support. See:

http://docwiki.embarcadero.com/Libraries/XE3/en/System.Classes.TComponent.Observers

http://docwiki.embarcadero.com/Libraries/XE2/en/System.Classes.TObservers_Methods

Recently observer support was added to fpc.

Just wondering what path fpc will follow:

1) Ditches the current fpc implementation and implements a Delphi
compatible interface

2) Time to diverge from Delphi. Keeps fpc own implementation

3) Implement both interfaces
