It's already on my radar since Delphi's NextGen compiler introduced ARC 
(Automatic Reference Counting) for TObject and its descendants.

Though while I'd like to implement them I don't consider them the holy 
grail especially since the programmer needs to take care of cycles in 
the objects (Delphi solves this by allowing the programmer to declare 
fields, paremeters and such as "weak", thus not changing the reference
