utable static items that implement <code>Sync</code> are safe, why is taking &amp;mut SHARABLE unsafe?</a></h3>
<p>Having multiple aliasing <code>&amp;mut T</code>s is never allowed. Due to the nature of
globals, the borrow checker cannot possibly ensure that a static obeys the
borrowing rules, so taking a mutable reference to a static is always unsafe.</p>
