<h3 id="Defer_statements">Defer statements</h3>

<p>
A "defer" statement invokes a function whose execution is deferred
to the moment the surrounding function returns, either because the
surrounding function executed a <a href="#Return_statements">return statement</a>,
reached the end of its <a href="#Function_declarations">function body</a>,

The variable used by each subsequent iteration is declared implicitly before
executing the post statement and initialized to the value of the previous
iteration's variable at that moment.
