Research direction

Start with the pidigits benchmark in pyperformance/data-files/benchmarks/bm_pidigits and review linked PRs gh-157743, gh-157744, and gh-157751. Read the proposal's references to rust-for-python and PEP 836 to understand the possible approaches; done would require a measurable improvement to pidigits and integer arithmetic, but the issue does not define a concrete implementation or acceptance target.
