That's more like it! The Dictionary4 slowdown is because of extra ARC traffic around item.hashValue, which I believe is there to protect the dictionary storage against a possible asymmetric release in _combineHashValues.

Adding @effects(readonly) to the definition of _combineHashValues will make the extra retain/release go away, restoring performance. Unfortunately, I'm not sure how we can promise the same thing in #14442's new interface.

Yay, it works! Now we just need to find out how to do the same sort of thing for #14442.

E.g., making the hash state update nonmutating would let us apply the same @effects(readonly) attribute to it, but we'd lose the attractively minimal API, and I'm not sure how out-of-place state updates would perform on SipHash's five-word state.
