In Kotlin, how to check contains one or another value? : <p>In Kotlin we can do:</p>

<pre><code>val arr = intArrayOf(1,2,3)
if (2 in arr)
   println("in list")
</code></pre>

<p>But if I want to check if 2 <em>or</em> 3 are in <code>arr</code>, what is the most idiomatic way to do it other than:</p>

<pre><code>if (2 in arr || 3 in arr)
   println("in list")
</code></pre>
