• [nitpick] Consider using explicit keyword arguments when instantiating MatchState (e.g., base_uncheckpointed_statements=self.uncheckpointed_statements.copy()) to improve clarity.

self.match_state = MatchState(self.uncheckpointed_statements.copy())

• [nitpick] The variable name 'blah' is ambiguous; consider renaming it to a more descriptive identifier.
