hash

(hash x)

clojure.core/hash: the hash consistent with =, the oracle's Util.hasheq and its numbers: Murmur3 over a long, a string, a keyword's or symbol's name and namespace, and a collection's members -- in order for a vector, list or seq, in any order for a map or set -- mixed with their count; a double, ratio, character, boolean, UUID and instant hash as their Java hashCode (both zeros 0), a record as the oracle's generated hasheq. A deftype or reify answers its IHashEq hasheq, else its hashCode override, else its identity, like a function or an atom: stable for the object's life, but not the oracle's number. As a value a function of one argument.
