I wouldn't call it a pitfall. Boost is written by C++ experts who like to push the boundaries of what can be done with the language. This doesn't mean that you have to debug their code or overuse templates yourself and there is nothing in the language that encourage this. For common cases such as in the standard library, templates are pretty easy to use and trivial to debug with modern compilers.
