Well, any CoffeeScript service which configured itself pre 1.2 without a `return` at the bottom, now returns the last value as the service instead of the service being the `this` object, which may be unwanted.

```
myApp.service 'applicationSrvc', ->
  @something = "value"
  @someFunct = -> 
    "something else"
```

pre 1.2 this would return the whole object as the service.

post 1.2 this returns `someFunct` as the value of the service

you would need to change services to
```
myApp.service 'applicationSrvc', ->
  @something = "value"
  @someFunct = -> 
    "something else"
  return
```
to continue to return the complete instance.

would you want the example as a part of the docs?
