Huh? I don't quite see what you're getting at here. The report says
that the trailing comma is allowed in import and export lists, yes.
But you were talking about trailing commas in lists and tuples, which
would be a change to the existing language, not something that's
"already explicitly allowed". Can you clarify what you meant?
Cheers,
