I'm not getting my question across. _How_ do you say this at the place 
you want to use the thing?

If the answer is "Just say the name of the thing!", then I ask: "How do 
you know which module the thing comes from?"

Even with package dependences rather than module dependences, you still 
need to say at the use-site which version of the package you want. 
Perhaps you are proposing "import java.util.List @ 8.0;" ?
