Just to clarify. + more intuitive for common reachability use cases than option 3 This applies for both options 6 + 7: Both defaulting to distinct paths and changing the semantivs of *,+ would be (as the recent discussions seem to indicate) more intuitive for simple reachability (*,+) use cases than defaulting to counting as in curent option 3 (where I understand that the resolution was to leave *,+ as in LC). '/', as well as mixed use cases where '*' and '+ 'are combined with '/' are an orthogonal issue, IMO. I am not entirely clear about what people fine more intuitive on '/', opinions welcome.
