Mixing both OOP models isn't a problem but e.g. streaming is a problem.

 From ide\text\fpdebug.pas:

  PBreakpoint=^TBreakpoint;
  TBreakpoint=object(TObject)
     typ  : BreakpointType;
     state : BreakpointState;
     owner : PBreakpointCollection;
     Name : PString;  { either function name or expr to watch }
     FileName : PString;
     OldValue,CurrentValue : Pstring;
     Line : Longint; { only used for bt_file_line type }
     Conditions : PString; { conditions relative to that breakpoint }
     IgnoreCount : Longint; { how many counts should be ignored }
     Commands : pchar; { commands that should be executed on breakpoint }
     GDBIndex : longint;
     GDBState : BreakpointState;
     constructor Init_function(Const AFunc : String);
     constructor Init_Empty;
     constructor Init_file_line(AFile : String; ALine : longint);
     constructor Init_type(atyp : BreakpointType;Const AnExpr : String);
     constructor Load(var S: TStream);
                         ^
TBreakpoint depends on the TV streaming. This is necessary because
the breakpoints are stored in the desktop file. But using TV streaming
in Lazarus is nonsense.
