Hi, I heard Rich Hickey talking about how identity in clojure is synonymous with value-based tests of equality. To make this efficient he describes that objects store cached hashes that are used to speed up these tests of equality, so clojure isnt comparing every data member of a complex data structure. However, how does this actually work since a comparison of hashes doesn't guarantee that two objects are equal. How does clojure handle the case where two hashes are the same for two distinctly different values.
