Once again, async Python requires different inference rules to sync Python!
A new
DefinitionNodeRef::ExceptStarHandlervariant is introduced, so that we can differentiate between except-handler definitions inStmtTry { is_star: true }nodes and those inStmtTry { is_star: false }nodes. The logic for adding these definitions is also moved inbuilder.rsso that we can know whether thetryblock is catching exceptions or exception groups. (We'll need to move the logic there anyway when adding control flow for these definitions.)Lots of TODOs here, but I think inferring
Instance(BaseExceptionGroup)is better than just inferringUnknownfor these definitions.The PR is stacked on top of #13319
