The analog for that would be shared literals which are not copied (super important for small map overhead reduction if the constructor initialized a fix set of keys like elixir structs as the key index is shared). The persistent_term module allows any value to be registered as such at runtime and avoids a lot of caveats that came with mochi_global and the like. While they aren’t ref counted it can definitely help cut down on copying in my experience.
