To be clear, I use this when I'm subclassing something and don't need to do anything with the _lazy other than set it to None in the __init__. I like this idiom because it removes the risk of miscalling the parent __init__, and it's also quick and easy to code. Yes there is a class member I am creating, but each instance has a distinct member. (In other words, I'm an adult, I tested it and it works, but I couldn't find anything in the Google indicating what the collective reaction would be from Pythonistan) -- https://mail.python.org/mailman/listinfo/python-list
