This is bogus. It doesn't do anything.
I had never seen code like that and it isn't documented as far as I can see.
To be sure I had a look at angularjs source code and found that the return
value is simply ignored.
Somebody correct me if I am wrong - maybe on some old version of ng it
actually did something?!
