Variable Injector

Allows performing injections outside the normal injection context window.

Example:

class Wizard {
  private injector = inject(Injector);

  // Lazily initialize the wand property
  private wand?: Wand;

  getWand(): Wand {
    // An injection context does not exist here, but the
    // Injector instance retains and reuses the context
    // that was present at the time of its injection
    return (this.wand ??= this.injector.inject(Wand));
  }
}
