[Python-Dev] PEP needed for http://bugs.python.org/issue9232 ?

So, there's a patch on issue 9232 - allow trailing commas in function definitions - but there's been enough debate that I suspect we need a PEP. Would love it if someone could correct me, but I'd like to be able to either categorically say 'no' and close the ticket, or 'yes and this is what needs to happen next'. -Rob -- Robert Collins Distinguished Technologist HP Converged Cloud
