[TYPO3-mvc] Benefit of DI when referencing to a class (and not to an interface)?

ok. thanks. i don't know that much about unit tests for now - but i 
trust you! ;-)

do you really reduce dependency with this?

--- quote ---

/**
  * @var Tx_Foo_Domain_Repository_BarRepository
  * @inject
  */
protected $barRepository;

--- /quote ---

aren't you still dependent on a class named 
Tx_Foo_Domain_Repository_BarRepository?

do i misunderstand the term "dependency"? does "dependency" mean the 
opposite of "decoupling" here?

maybe is should not worry that much about terms and definitions?

kind regards

roland
