I'm probably missing something, but a straightforward reflection approach seems to work on my machine: >>> restrict() >>> readonly_facet = facet(counter, ['value']) >>> print readonly_facet.value() 0 >>> readonly_facet.value.im_self.n = "oops!" >>> print readonly_facet.value() oops! >>> class mycounter: ... def value(self): return "muhaha!" ... >>> readonly_facet.value.im_self.__class__ = mycounter >>> print readonly_facet.value() muhaha! ... >>> readonly_facet.value.im_func.func_globals["readonly_facet"] = myinstance ... and so on does that restrict() function really do the right thing, or is my python install broken? </F> _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
