use deftype which is more low-level and I think doesn't define equals or
put y in meta data that don't participate in equality...:)

defrecord does not support Java class inheritance, so it cannot
override methods of Java classes, even abstract classes. However,
it does permit you to override methods of java.lang.Object such as
hashCode, equals, and toString. Simply include java.lang.Object in
the defrecord as if it were an interface. Clojure will generate
good value-based implementations of the hashCode and equals
methods, so it is rarely necessary to implement them yourself.
(defrecord R [x y] java.lang.Object (equals [_ r](= x(.x r))))
--> Duplicate method name&signature in class file
