+<p>Ruby 2.7 introduced beginless ranges. But, unlike the somewhat obscure <code>-1</code> in <code>ary[1..-1]</code>, the <code>0</code> in <code>ary[0..42]</code> is clear
+as a starting point. In fact, changing it to <code>ary[..42]</code> could potentially make it less readable. Therefore, <code>ary[0..42]</code>
+should respect the original programmer&#8217;s intent. On the other hand, <code>ary[nil..42]</code> could be replaced with <code>ary[..42]</code>.
+Similarly, <code>ary[1..nil]</code> could be replaced with <code>ary[1..]</code>.</p>
