[New-bugs-announce] [issue35798] duplicate SyntaxWarning: "is" with a literal

[Jakub Wilk]

New submission from Jakub Wilk <jwilk at jwilk.net>:

$ python3.8 -c 'if object() is 42: pass'
<string>:1: SyntaxWarning: "is" with a literal. Did you mean "=="?
<string>:1: SyntaxWarning: "is" with a literal. Did you mean "=="?

I'd like only one copy of this warning, not two.

Tested with git master (e9b185f2a493cc54f0d49eac44bf21e8d7de2990).
