What about adding rule about trailing comma?
My crystal ball tells me that you're possibly talking about PEP 8 rather than about actual language changes. Is that correct? There's absolutely no need to put restrictions like this into the language itself. If the trailing comma is permitted, it should be permitted whether there's a newline after it or not. In your own style guide, you're most welcome to advocate what you will, without needing any approval from the Python core devs. If you want to say, for instance, "we follow PEP 8, with the following additional requirements", and then list your trailing comma rule and any others you want to require, people will understand. Actually, most people will do something like this, anyway. ChrisA
