I strongly disagree.  '<>' is not a legal operator any more.  It is a parse-time syntax error.  Whatever historical artifact is left in the CPython tokenizer, recognizing '<>' is not exposed to Python code.

>>> p = ast.parse('a <> b')
Traceback (most recent call last):
...
    a <> b
    ^
SyntaxError: invalid syntax  

When '<>' was legal, we may presume that tokenizer recognized it, so that not recognizing it was an intentional change.  Reverting this would be a dis-service to users.  

I think that the PR and this issue should be closed.  If the historical artifact bothers you, propose removing it instead on introducing a bug into tokenizer.
