Clojure records are named classes that implement IPersistentMap so they're a drop-in replacement for "normal" maps, that also implement an additional interface so the compiler can generate java field lookups to access items without the cost of a hash lookup. Awesome! Thank you for that. I saw people referring to it as a hash when you point out it is not, so I was confused. I sit corrected as well as happier with the Clojure design.
