<code>
let fn2: ((Int, Int)) -> Void = { lhs, rhs in }
</code></p>
<p>Instead use destructuring sugar pitched by Chris Lattner on the other thread:</p>
<p><code>let fn2: ((Int, Int)) -> Void = { ((lhs, rhs)) in }</code></p>
<p>That’s a correct error:</p><span class="">
<pre><code>let fn3: (Int, Int) -> Void = { _ in }
</code></pre>
</span><p>This should be allowed, because we might want to work with the whole tuple and not a desctructured elements only:</p>
<pre><code>let fn4: ((Int, Int)) -> Void = { tuple in }
