[FLOW3-general] how to param function with longer package name

[Dawid Pacholczyk]

Hi List,
  I want to param a method in my model. I named my package like the new 
Framework packages - with dot

Key.name

Now. How I should param a method ?

I`ve done something like this:

public function \TYPO3\Key.name\Domain\Model\Class

but I get an error

syntax error, unexpected '.'

How should I do it ?

Best regards,
