title: Can I comment multi-line macros?
body: <p>I'm writing a few large macros and thought it'd be nice if I could add comments to them, like this:</p>
  
  <pre><code>#define SOME_BIG_MACRO(input)\
    SOME_FUNCTION_CALL() \ // this does...
    SOME_OTHER_FUNCTION_CALL()
  </code></pre>
  
  <p>When I run this I get:</p>
  
  <blockquote>
    <p>prog.cpp:9:2: error: stray ‘\’ in program</p>
  </blockquote>
  
  <p>Is there any way around this, or is it just not possible to comment mult-line macros?</p>
