Well, up to this moment I was pretty sure your parser is the parser in the
conventional sense (LR or LL) :-)

Ah, so this is command line parser! Actually, I have been promising to finish
one soon for a long time. At this moment what is missing from my code is
support for sundry styles of options and checking from ambiguity. From code
examples that you've given, I'm not sure about:
i) Can be have validation of input arguments
ii) How such thing as '-I' option to a compiler may be implemented (example
ii) Is there low-level access to parsed options, such as in form of
vector< pair<string,/*option*/ string /*value*/> >
