(hash-ordered-coll coll)

clojure.core/hash-ordered-coll: the hash = keeps for an ordered collection, computed over any Iterable (a vector, list, seq, map, set, record, sorted collection, a type implementing Iterable, a Java collection): from 1, 31 times the running hash plus each member's hash, mixed with the count, so it equals hash of a vector of the same members. A map's members are its entries. nil is the oracle's NullPointerException and a value that is no Iterable (a string, a number, a keyword) its ClassCastException.
