Are you suggesting we implement ARC?
Yes. -- Andrei
I don't think ARC is needed.
library RC + borrowing + uniqueness/moving = WIN
You can't do polymorphic entity RC (like exceptions) without at
least some help from compiler because language currently does not
provide tools for lifetime control of classes. At least _some_
form of ARC is necessary.
