Actually, the very first observation I made is that, if you try to assign a value to '...', the traceback includes the message: SyntaxError: cannot assign to Ellipsis which is clearly wrong. If it would state: SyntaxError: cannot assign to '...' the only inconsistency left would be a more minor one, that is of the repr of '...' stating that it is Ellipsis which can be incorrect if Ellipsis is bound to a different value. Sorry for opening what became a rabbit hole of a discussion. André > The repr of '...' should be more self-explanatory to beginners.
