> objects that might know about pointers to them The Pin<> type constructor is being standardized to support this case. This is not so much "custom move semantics" as a lack of in-built "move" semantics of any sorts, but the basic use case is being worked on. > And does the compiler no longer complain about code that really should work just fine? As other people have mentioned, the NLL feature addresses many cases where this used to be a problem, and has now been introduced to the 'stable' version.
