When Clojure starts, it searches for files named 'data_readers.clj' and 'data_readers.cljc' at the root of the classpath. Each such file must contain a literal map of Such functions either use the clojure.core/lazy-seq macro or other functions that produce lazy sequences. clojure.core/lazy-seq accepts one or more forms that produce a sequence of nil (when the sequence is fully realized) and returns a seqable data structure that invokes the body the first time the value is needed and then caches the result.
