Good point, didn't think of that. Although... since that's an arbitrary placeholder, it could be changed to pretty much anything. Maybe <...> or something? The current repr may not technically be ambiguous, but it will silently do the wrong thing if you try to eval it. You can even ast.literal_eval(repr(a)) and it'll appear to work. Not a huge deal whichever way, though. The token "..." is used in a variety of non-ellipsis ways, such as doctest, and that isn't inherently a problem.
