title: Empty/delete a set in Redis?
body: <p>Maybe I'm just blind, but I don't see an explicit <a href="http://redis.io/commands#set" rel="noreferrer">set command</a> in Redis for emptying an existing set (without emptying the entire database). For the time being, I'm doing a set difference on the set with itself and storing it back into itself:</p>
  
  <pre><code>redis&gt; SMEMBERS metasyn
  1) "foo"
  2) "bar"
  redis&gt; SDIFFSTORE metasyn metasyn metasyn
  (integer) 0
  redis&gt; SMEMBERS metasyn
  (empty list or set)
  </code></pre>
  
  <p>But that looks a little silly... is there a better way to do this?</p>
