<p>Here is an updated example that would work:</p>

<div>No, again, this would be banned. You are using a label (a
thing that ends in a colon) inside a tuple pattern (a thing between
parenthesis that comes after "let").</div>

<p>It’s assigning the inner tuple to <code>second</code> while also
creating two additional constants from the inner tuple. I know this
is redundant and can be used as <code>second.x</code>, but this
should work like right, because it’s nested tuple destructuring? If
we’d use <code>var</code> instead of <code>let</code> then
<code>x</code> would contain the value assigned from the inner
tuple, but it would be completely independent from the new
<code>second</code> tuple variable.</p>
