Which example you're referring to?

I don't know of any efforts going on regarding C++ parsing with the help of
regex (non-authoritative answer). But there is the Wave library (Boost
review is due shortly), which is a C/C++ preprocessor containing different
C++ lexing components, which may be helpful for you during writing a class
name extraction tool.
