How to use @glimmer/tracking - 2 common examples

get(_target, prop) {
        if (capturedArgs.named.has(prop as string)) {
          let ref = capturedArgs.named.get(prop as string);
          consume(ref.tag);

          return ref.value();
        }
      },

function tracked(target: object, key: string, desc: PropertyDescriptor) {
  let initializer = (desc as any).initializer;
  let trackedDesc = glimmerTracked(target, key, desc);
  let { get: originalGet, set: originalSet } = trackedDesc;

  let defaultAssigned = new WeakSet();

  function set(this: any, value: unknown) {
    if (typeof value === 'object' && value !== null) {
      if (value instanceof Map) {
        value = new TrackedMap(value);
      } else if (value instanceof WeakMap) {
        value = new TrackedWeakMap();
      } else if (value instanceof Set) {
        value = new TrackedSet(value);
      } else if (value instanceof WeakSet) {
        value = new TrackedWeakSet();
      }
    }
