[New-bugs-announce] [issue44278] Improve syntax error message for assigning to "..."

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Some users can be confused by syntax error message for assigning to ellipsis [1]:

>>> ... = 1
  File "<stdin>", line 1
    ... = 1
    ^^^
SyntaxError: cannot assign to Ellipsis here. Maybe you meant '==' instead of '='?

because Ellipsis is a name of a builtin variable Ellipsis, and it is possible to assign to variable named Ellipsis.

>>> Ellipsis = 1
>>> Ellipsis
1

I think that using lowercase spelling of "ellipsis" will eliminate confusion.
