I have the following question. I want to subclass/implement a new position_iterator that recognizes lines such as:

#line 11 "electrical.lcl"

and updates accordingly its location.

My question is how to do that in the most elegant manner. Shall I copy/paste "position_iterator.hpp" and hack the increment() method? Would you, guys, use a Qi parser to recognize these lines? Maybe there is a better way...
