Haskell conduit filter distinct values
<p>If I use the following <code>Source</code>:</p>

<pre><code> sourceList [1,3,3,1,2,3]
</code></pre>

<p>Is it possible to apply some filter or combinator to only allow distinct values to be passed downstream?</p>

<p>So in my example, only <code>[1,3,2]</code> would be passed downstream?</p>
