<p>I would like to propose an improvement to an initializer of all collection types that provide: <code>init(repeating repeatedValue: Element, count: Int)</code>.</p>
<p>This change is meant to support reference type initialization on each iteration of the internal for-loop rather than copying the same references n times.</p>
<p>The change would be really straightforward and should not break existing code, except that the behavior would change for class types.</p>
<p>Instead of:</p>
<p><code>init(repeating repeatedValue: Element, count: Int)</code></p>
<pre><code>let threeViews = Array(repeating: UIView(), count: 3) // contains 1 view 3 times
</code></pre>
<p>we would have:</p>
<p><code>init(repeating repeatedValue: @autoclosure () -> Element, count: Int)</code></p>
<p>This simple change would allow us to construct an array of different objects instead of an array with n references to the same object.</p>
<pre><code>let threeViews = Array(repeating: UIView(), count: 3) // contains 3 different views
</code></pre>
