New submission from Sergei Lebedev <slebe...@google.com>:
Reproducer: [x for x in [] if lambda: x] This parses fine in 3.8, but doesn't parse in 3.9 because the grammar expects a disjunction after if in for_if_clause [*]. While this change has zero practical significance, I think it might be useful to maintain a list of such changes for tooling authors (who might need to support multiple Python versions).
