As I understand it (and there will certainly be hell to pay if this is not true), the rewrite of MacApp in C++ will NOT use any features of C++ that Object Pascal doesn't have, e.g. constructors and destructors.  To do so would be to abandon all of the Object Pascal users who have hung in with MacApp through thick and thin over the last 5 years or so.
