Research direction
Start by reviewing the existing python/cpython#26697 pull request and the referenced matchperf.py benchmark. Determine which safe match-case statements are in scope and how the jump-table change should be evaluated; the work is done when the targeted cases use the intended optimization and the relevant performance behavior is verified.
