title: Redis fetch all value of list without iteration and without popping
body: <p>I have simple redis list key => "supplier_id"</p>
  
  <p>Now all I want it retrieve all value of list without actually iterating over or popping the value from list</p>
  
  <p>Example to retrieve all the value from a list Now I have iterate over redis length</p>
  
  <pre><code>element = []
  0.upto(redis.llen("supplier_id")-1) do |index| 
    element &lt;&lt; redis.lindex("supplier_id",index)
   end
  </code></pre>
  
  <p>can this be done <strong>without the iteration</strong> perhap with better redis modelling . can anyone suggest</p>
