async-object-stack

A wrapper of AsyncLocalStorage that keeps a stack of objects. Supports the using syntax to automatically pop objects from the stack when the current scope ends.

Primary use case is creating a nice API for structural logging. See Structural Logging Example.

{
  using guard2 = stack.push({ bulba: "saur" });
