title: Do lambdas get inlined?
body: <p>Do simple lambda expressions get inlined?</p>
  <p>I have a tendency (thanks to F# and other functional forays) to encapsulate repeated code present within a single function into a lambda, and call it instead. I'm curious if I'm incurring a run-time overhead as a result:</p>
  <pre><code>var foo = a + b;
  var bar = a + b;
  </code></pre>
  <p>vs</p>
  <pre><code>Func&lt;T1, T2&gt; op = () =&gt; a + b;
  var foo = op();
  var bar = op();
  </code></pre>
  <p>Which one costs more to run?</p>
