When considering how this should work, I would strongly suggest 
it be the default to work with the current edition of the 
language. Nobody wants to always have to attribute their module 
(or whatever other opt-in mechanism) to use current features. 
It's going to be a WTF moment for all newcomers to D.

This brings us to the problem that no prior libraries have 
editions marked on them. So I think there needs to be an external 
mechanism to be able to set the edition for a package or module 
from the command line, or somehow in a config file. Or you can 
set the "assumed" edition using a switch (but it should still 
default to "current").
