Example code for the problem of removing items from lazy sequences nested in a large Clojure tree and related issues. See http://stackoverflow.com/questions/32667778/removing-elements-from-lazy-sequences-in-a-large-clojure-tree-structure-avoidin for details
(ns large-tree.core
"Working example, also using XML."
(require [clojure.data.xml :as xml]))
(defn root' [content]
(fn []
(xml/map->Element {:tag :root :content (content)})))
(defn lazy-elements' [n tag content]
(repeatedly n (fn [] (xml/map->Element {:tag tag :content (content)}))))
