In Python `...` is referred to as `Ellipsis` and cannot be assigned to. Yet, one can assign any value to the name `Ellipsis`.
Consider the following:
```
... Ellipsis ... == Ellipsis True Ellipsis Ellipsis Ellipsis = 3 Ellipsis 3 ... = 4 File "<stdin>", line 1 ... = 4 ^ SyntaxError: cannot assign to Ellipsis # But I just did assign a new value to the name Ellipsis above. Ellipsis 3 ... Ellipsis ... == Ellipsis False
For consistency, `Ellipsis` (the name) should **always** refer to the same object that `...` refers to, so that both could not be assigned a new value.
Perhaps Ellipsis could get the same treatment as None here, but I am not sure if there's enough reasoning to justify that, especially considering that it would be a backwards incompatible change. Do you have any use-cases that would warrant such a thing? I find it incredibly hard to justify this proposal. Cheers, Filipe Laíns
