Some C++ wizards took Greenspun's 10th rule as a challenge and developed template metaprogramming libraries like Loki and Boost :P Its kind of interesting to observe how C++ typelists do compile-time metaprogramming, they use a cons linked-list of types in templates. Its kind of sad to watch though because there's no REPL to set the cons free.
