Do we have a plan for how to implement this? The RFC doesn't specify how to do it, and this is…a lot of work because of the way vtables work. I'm a little unhappy with the scope creep here. :(

Since this is almost entirely unimplemented, there are no current 1.0 blocking parts of it.

(if we were to implement it only partially, then it would become a backwards compatibiilty risk.)

This needs a volunteer to implement.

Nominating for 1.0 P-backcompat-lang due to the desire to use this in important types like HashMap.
