And for times you need a fast heap-allocated type, Swift's Noncopyable types have been pretty great in my experience. Especially so for graph data structures, where previously retains/releases would be the biggest slowdown.

An added plus is that the Swift compiler seems to stack-promote a lot more often, compared to class/ManagedBuffer implementations.
