Layering assoc calls are hard to read. assoc-in is known and idiomatic.

Examples:

; bad (assoc coll :key1 (assoc (:key2 coll) :key2 new-val)) (assoc coll :key1 (assoc (coll :key2) :key2 new-val)) (assoc coll :key1 (assoc (get coll :key2) :key2 new-val))

; good (assoc-in coll [:key1 :key2] new-val)
