Heh, I feel you. Test were indeed used to verify that your code runs correctly and with edge cases, and stuff like isinstance were discouraged so you wouldn't need to think about types but rather of interfaces. However I assume that a large influx of people who had experience with typed languages had changed general idea of how Python should look and be used. Oh well, times change and we all allowed it so... types it is :/
