Hmmm...stated another way: I am proposing that the list and tuple syntax change to be consistent with the import and export syntax. The argument that a trailing comma "means" "the programmer forgot the last item" in a list / tuple is inconsistent with the deliberately explicit permissiveness of a trailing comma in the import / export lists. In the import / export lists such a trailing comma does not mean "programmer forgot additional thing at the end."
Ok, now I see your point. I agree it does seem inconsistent. I don't know the reasons for the choice to make the import/export lists work that way, but I would guess that it's because when people use import/export lists, they often add/remove items from the lists, and allowing the trailing comma just makes things easier. On the other hand, with constant lists and tuples, you're probably not going to frequently edit the same constant list value. Am I missing something?
