Marking itself does not help here. The mark-function of a PMC is called after it is already marked. Self-marking does nothing in the best case, in the worst case it blocks the DoD in an endless loop. Anyway a weakref needs to extend the destroy-function of the refered object (on a per object basis). This is whats not possible in current parrot. Parrot_exit/Parrot_on_exit does something similar but not for the destruction of an object but for the end of the program. bye boe -- Juergen Boemmels [EMAIL PROTECTED] Fachbereich Physik Tel: ++49-(0)631-205-2817 Universitaet Kaiserslautern Fax: ++49-(0)631-205-3906 PGP Key fingerprint = 9F 56 54 3D 45 C1 32 6F 23 F6 C7 2F 85 93 DD 47
