A non-working prime number generator

prime.clj

(ns clojure-noob.prime
  (:require [clojure.string :as string])
  (:gen-class))
(defn N-stream []
  (defn from
    [n]
    (cons n (lazy-seq (from (inc n)))))
  (from 1))
(take 1000 (N-stream))

;;PRIME GENERATOR HELPERS
;; not eq zero test
(defn nz? [x]
  (not (zero? x)))
;; a%b!=0?
(defn modnz? [a b]
  (nz? (mod a b)))

;; prime generator
(defn prime-stream
  ([] (prime-stream (N-stream)))
  ([xs]
   (cons (first xs) (prime-stream (filter #(modnz? % (first xs)) (rest xs) ) ))))
(take 10 (prime-stream))

This runs forever until a java OutOfMemoryError happens ☹️

Unfortunately I don't have time to analyze this but one thing that popped out at me is that you are defining from within the N-stream function, which seems like it would cause problems.

There are usually folks in the clojure subreddit, http://www.reddit.com/r/clojure, who are able to help folks out. Good luck!
