<p><code>jumps</code> tells you if an expression, or an internal part of an expression

has a flow control construct (like <code>break</code>, or <code>continue</code>, or <code>return</code>,

or <code>throw</code>) that jumps out of the normal flow of control and can’t be

used as a value. This is important because things like this make no sense;

we have to disallow them.</p>
