That would be too easy :)
Actually that was just an example, the real cause is more complex,
and my goal is to save all informaion encountered while parsing
subexpression amd process it as a whole when it's finished. Like
that:
char *a_start;
char *a_end;
a = 'a'+
> { a_start = p; }
% { a_end = p; }
;
b = a 'b'+
> { a_start = a_end = 0; /* reset state */ }
% { printf("subexpr finished, there were %d a's\n", a_end-a_start); }
;
main := b+;
