Re: Critique of PEP 622 (Structural Pattern Matching)
(the example with changing HTTP_OK value is downright horrifying).
As was just mentioned by Guido in another thread, there is a SyntaxWarning to alert you.
This leads to the idea that, if a special syntax if eventually used for Value Patterns, using the comparison operator in it might be useful.
Have a look at https://www.mail-archive.com/python-dev@python.org/msg109254.html . Unfortunately, this doesn't scale well with attribute checks... Cheers, Jean Abou Samra

That doesn't help if the symbolic constant is the last match. Also, it's only in the reference implementation. It's not in the specification.
