   Haven't you always wanted to write an entire lisp (or   
   haskell or c++ or...) compiler as a template metaprogram so you can   
   embed that language in your C++ code?  ;-)   
      
   Everything we might do with template metaprogramming today can now have   
   arbitrary syntax, without the limitations imposed by C++, if you're   
   willing to write the programs inside user-defined literals.
