probably the best C++ parser...

As I've mentioned already, gccxml does not say anything about function bodies,
so there still should be code to decided that 'v' variable is std::vector and
not my_namespace::vector, and not my_base_class::vector, and what not.
IMO, the optimal solution would be to use gcc parser running in background.
So, as you type, the parser will consume the tokens you've typed, and provide
exact information about type/members and so on.
That would require, however, some support for rewinding -- so if you edit in
the middle of the file, parser forgets previously read reminder of the file.
Another C++ parser I know about is Synopsis
(http://synopsis.sourceforge.net/), which is reported to even parse Boost.
At this point, I'm not quite sure if hacking gcc or improving Synopsis is the
best way to go.
