C, C++

In my experience as a programmer, I have noticed that there always has been demand for a good way to achieve class introspection. Then the arguing starts: some languages already have class and object introspection, like Obj-C or Python, which, though becoming increasingly more popular, are still the minority of used languages. Then we have C++, which doesn't have class introspection by default, but most people use a lot. Is there a solution to this problem? Surprisingly, physicists have developed a great tool!
