3.14 and 3.13 differ from main, so I would do backporting step by step. |
|
If we can detect this in https://github.com/python/cpython/blob/main/Python/ast_preprocess.c then we get the warning in both static analysis and execution. |
|
Yes, but we only add SyntaxWarning for very common errors. |
|
Is it hard to detect this in the preprocessor? |
|
I do not know. But even a couple lines of code is a high price for this feature. And it will be more than a couple lines. |
