after beeing back from weekend it looks like I have stirred up a 
hornet's nest. As Alisdair already pointed out I don't depend on boost 
anymore. In turn I now depend on std::tr1 and the fancy features of 
std::tr1::function. And after a quick view through my code I came to the 
conclusion that I don't want to miss these features. However you should 
note that only my AST processing depends on tr1. No tr1 dependency is 
injected in existing modules. That said I don't like the argument about 
the usage of 'insane' C++ constructs only. Whether std::tr1::function is 
still insane I don't want to justify. But IMHO everone working on AST 
processing should have a basic understanding of lambda calculus and all 
that stuff around.
