## New (17)

- Asymmetric API between sync and async benchers. AsyncBencher has `iter_with_large_setup` but Bencher does not have a corresponding `iter_with_large_setup` (it only has `iter_with_setup` and `iter_with_large_drop`). This forces users to handle setup/drop logic differently depending on the executor type.
- Duplicated block (6 lines × 2) (src/plot/gnuplot_backend/regression.rs)
- Inconsistent ID type for benchmark identification. The top-level Criterion API expects a string for the benchmark ID, while the BenchmarkGroup API expects a specific BenchmarkId type.
- Inconsistent ID type for parameterized benchmarks. Criterion expects BenchmarkId, while BenchmarkGroup uses a generic ID type (likely String or BenchmarkId depending on context, but the signature differs).
- Low cohesion: Sample (LCOM4 5) (src/stats/univariate/sample.rs)
