This RFC is based on @gankro’s proposal at https://gist.github.com/Gankro/b053cb4d1cb3bcaec070de89734720f7. By the time I got it into a submittable state however, I because increasingly convinced that it would be better replaced by a more general design that would apply not just to trait objects but all pointers, with an associated type for (fat) pointer metadata. I’m submitting this as a PR anyway for posterity and comparison, but I’ll be closing it immediately.
