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'.
