Hi all,
This has been a fantastic discussion, and the pitched proposal has been improved and clarified considerably along the way. While there are still some things under discussion here in the pitch thread, the Core Team feels that the proposal and discussion has converged enough to initiate a review. Those discussions that would directly impact the proposed features (e.g., the alternative Any<P> syntax still under discussion) can certainly move to the review thread, where we'll get opinions from others who follow formal reviews but not pitches. But we should be mindful of scope creep: other discussions around extensions to the proposal model that wouldn't change the meaning of what's proposed (e.g., introducing a new kind of metatype for protocols) can continue here or be handled through other threads as well.
Thanks everyone, I'll launch the review shortly.
EDIT: Review thread is here
Doug
