I skimmed the old threads, and with the benefit of hindsight this seems a lot less mysterious to me now. I completely forgot that the RFC which got postponed never really incorporated any of the feedback and bore almost no resemblance to the strawmen proposals we were throwing around in the old internals thread. In particular, none of the issues in Rfc: delegation of implementation by contactomorph · Pull Request #1406 · rust-lang/rfcs · GitHub apply to our current draft. Within the old internals thread itself, the only strong concern was 3 weeks to delegation! Please help - #33 by withoutboats which I believe is a non-issue with our current draft because arbitrary expressions and static methods are now considered potential extensions.
