What are the most surprising elements of the C++ standard?
<p>I've decided to get more acquainted with my favorite programming language, but <em>only</em> reading the standard is boring.</p>

<p>What are the most surprising, counter-intuitive, or just plain weird elements of C++? What has shocked you enough that you ran to your nearest compiler to check if it's really true?</p>

<p>I'll accept the first answer that I won't believe even <em>after</em> I've tested it. :)</p>
