The techniques he used are very similar to "Expression templates". If you are a C++ programmer and haven't heard of it, look it up. There are not many libraries actually making use of it, but Boost uBLAS is an example. I think expression templates give you a good idea what one can achieve with C++ (whether this is a good idea is another question).

OT: That's also why I love the language - there are plenty of ways to solve a problem and C++, unlike other languages, does not force me to solve a problem "the right way".
