title: Native infinite range?
body: <p>Does python have a native iterable of the infinite integer series?</p>
  
  <p>I've tried <code>range(float('inf'))</code> and <code>iter(int)</code>, but neither work.</p>
  
  <p>I can obviously implement my own generator along the lines of</p>
  
  <pre><code>def int_series(next=1):
      while True:
          next += 1
          yield next
  </code></pre>
  
  <p>but this feels like something which should already exist.</p>
