I don't think so: http://docs.python.org/library/weakref.html#weakref.ref """the weak reference object will be passed as the only parameter to the callback; the referent will no longer be available.""" -- Amaury Forgeot d'Arc _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
