/**
* A unique object used for retrieving items from the {@link ReflectiveInjector}.
*
* Keys have:
* - a system-wide unique `id`.
* - a `token`.
*
* `Key` is used internally by {@link ReflectiveInjector} because its system-wide unique `id` allows
* the
* injector to store created objects in a more efficient way.
*
* `Key` should not be created directly. {@link ReflectiveInjector} creates keys automatically when
* resolving
* providers.
* @deprecated No replacement
