Ooooh. Ok, I assumed the output of vector<Range> conflict would be
overlapping *source* ranges (apparently I didn't read closely enough, no
idea how I convinced myself that this makes sense :P)

In that case I'd suggest to either:
- use pair
- report conflicts as source ranges (which I'd personally prefer)
obviously fine as a follow-up patch.

Thanks!
