<p>Take a look at the top answer (by sclo) to problem D of this <a href="http://code.google.com/codejam/contest/scoreboard?c=32003#vf=1" rel="nofollow">Google Code Jam</a>. It's C++ code, it must have compiled, and it contains statements such as this one:</p>

<pre><code>double&amp; ret = F[mask][cur][b];
if(j==cur) {
  ret&lt;?=f(tmp,j,b||bad[i])+M[cur][i];   // WTF is &lt;?=   ???
}
</code></pre>

<p>This doesn't compile in my Visual Studio 2008. What does the <code>&lt;?=</code> mean?</p>
