<p>For the first statement:</p>
<ol>
<li><code>1</code> is an expression, so it has the fresh literal type <code>1</code>.</li>
<li><code>1: 1</code> is assigned to <code>const one</code>, which is not mutable, so <code>one: 1</code>.
But the type <code>1</code> is still fresh, which will be important later.</li>
</ol>
