This doesn't seem to work, the first time you setattr on hdlns.x, it will recursively doing so due to setattr(self, attr, value). I do understand you need override __setattr__() to provide an on demand signal creation, and you do need to call setattr() again to actually activate the descriptor, so stack eventually overflows. With a bit modification it can work, e.g. the last setattr(self, attr, value) should explicitly invoke SignalBehavior().__set__() instead. _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
