title: Variable name from macro argument
body: <p>I'd like to do something like this:</p>
  
  <pre><code>class SomeClass { };
  
  GENERATE_FUNTION(SomeClass)
  </code></pre>
  
  <p>The <code>GENERATE_FUNCTION</code> macro I'd like to define a function whose name is to be determined by the macro argument. In this case, I'd like it to define a function <code>func_SomeClass</code>. How can that be done? </p>
