What facilities does GPC have for forward defining types.
In CW Pascal, I have some code that looks like this:
[...]
   MyObjectB = object;
     f: MyObjectA;
    // other references to ObjectA
   end;
(btw Does this compile? Note the semi-colon after object)
Yes, the semicolon seems wrong (at least in other dialects).
...
Delphi supports this: (remember its object model is similar)
Type
    MyObjectB = class; 
    MyObjectA = class;
This seems to be what `class .. end' is in OOE.
...
Must be in one typeblock though, IOW, the same system as pointers.
Yes, same in OOE.
