![]() ## Summary In the latest release, we made some improvements to the semantic model, but our modifications to exception-unbinding are causing some false-positives. For example: ```py try: v = 3 except ImportError as v: print(v) else: print(v) ``` In the latest release, we started unbinding `v` after the `except` handler. (We used to restore the existing binding, the `v = 3`, but this was quite complicated.) Because we don't have full branch analysis, we can't then know that `v` is still bound in the `else` branch. The solution here modifies `resolve_read` to skip-lookup when hitting unbound exceptions. So when store the "unbind" for `except ImportError as v`, we save the binding that it shadowed `v = 3`, and skip to that. Closes #5249. Closes #5250. |
