    I want to create a hierarchy (or something) but i fall into this
    situation:

    TA = class
      C: TC
    end;

    TB = class
      A: TA;
    end;

    TC = class
      B: TB;
    end;

    TC - the type of C field of class TA if "Undeclared identifier"
    because it is declared below declaration of class TA.
    If this was function declarations, the "forward" directive is the
    solution of this problem, but what about classes?...

    ...one solution is this
    TCParent = class
    end;

    TA = class
      C: TCParent
    end;

    TB = class
      A: TA;
    end;

    TC = class(TCParent)
      B: TB;
    end;

    ...is there anything else?
