It's only conceptually similar to the "bump allocation in the nursery" part of garbage collection, IMO, as it skips the whole tracing part that makes RC, GC, and even RAII substantially less efficient than stack allocation. When people talk about GC having great performance compared to manual memory management they are very often only considering objects that die before the first major collection.
