I think making 'Ellipsis' a reserved word is too much. The analogy with
non-reserved words like `int`, `str`, `map`, `print`, and so on, illustrate
this, I think. I.e. redefining those is likely to cause bad things to happen,
but we're consenting adults, and in the end they are just names.
However, I think improving the repr() of the Ellipsis object itself to remind
users of the connection with its special literal `...` is a great idea.
Originally, the notation "..." could only be used inside a subscript,
and anywhere else, you'd have to spell it "Ellipsis". Now that you can
use "..." anywhere, would it be worth switching the repr to just be
that?
I feel like that might be confusing. We do have things like lists
where the repr of an empty list is [], but lists are pretty basic and
ubiquitous Python objects that people usually learn about quite early.
Ellipsis is a more obscure thing so it seems worthwhile to label it
somehow rather than just giving a cryptic three dots.
