I dunno... I took a look at a single file and found: static constexpr unsigned NUM_SLOTS = Policy::kSlotNum; static constexpr unsigned BUCKET_CNT = Policy::kBucketNum; static constexpr unsigned STASH_BUCKET_NUM = Policy::kStashBucketNum; NUM_, _CNT, _NUM, three different prefix/suffix for what seems to me like the same concept. That just tickled my inner nit-picker.
