A bit off-topic, but I wanted to clarify something, in case my many questions sound negative:
I think you guys have done a tremendous job with Jigsaw, and IMO the hardest is behind you, I can see there was a huge amount of work (well, you started it in Java 7…) to get to his point, and I feel that the rest will be much smaller and easier. That doesn't mean I agree with everything that was done or that some things still need attention, but honestly, as someone who did most of the modularity work in Ceylon, I know modularity is not a SMOP, it's a real hard problem, and given your constraints I think it's pretty amazing what you have accomplished so far. As a dev I know we hear complaints more often than appreciation, so thought I'd clarify that ;)
