Clean Context

[martinheidegger]

Having complex systems with various variables could result in leaking unintended values to subsystems. It might be reasonable to have something like AsyncContext.sandbox(() => {... }) which reset's all the state, preventing parents to interfere.

const asyncVar = new AsyncContext.Variable();

// Sets the current value to 'top', and executes the `main` function.
asyncVar.run("top", main);

function main() {
    AsyncContext.sandbox(() => {
      console.log(asyncVar.get()); // => undefined
    });
}

Just for context, in Node.js this is store.exit(() => {}).
