+
+    \brief Outputs emptiness.
+
+    ... = any variadic parameters. The parameters are ignored.
+    
+    This macro is used to output emptiness ( nothing ) no matter
+    what is passed to it.
+    
+    If you use this macro to return a result, as in 'result BOOST_VMD_EMPTY'
+    subsequently invoked, you should surround the result with 
+    BOOST_VMD_IDENTITY_RESULT to smooth over a VC++ problem.
