This "implicit referencing" isnt just for objects, you can use it for record
structures as well.
TRecordA = record
value : integer;
end;
TRecordB = record
recordA : ^TRecordA;
end;
recordB.recordA.value := 123;
>However, IMHO, OO programming ought not to use records anyway.
Why not? Should something simple like TPoint be an object? Objects can
also be a nuicense when you just want to hold and pass around simple data.
I still use records or the old BP7 object model sometimes for simple data
types.
i.e.
TMyPoint = object
public
x, y : double;
function length : double;
...
end;
You can define arrays of them, pass them around by value, you dont have to
dynamically create and destroy them etc etc.
