This is a set of helpers for finding the application's currently active models/routes/controllers/etc. This isn't a straightforward process because of how Ember (rightly) encapsulates application objects, but it's useful in debugging environments to be able to quickly access them. And with the beta release of Ember Data, the store is not easily accessible without helpers either.
All helpers can be called directly if you provide them an application instance:

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
