Well, I think if a library wants to branch on the edition of the caller, 
all of those branches would need to be compiled when the library is 
compiled. (Think druntime.)

Of course, the case where a library wants to branch on its own edition 
is separate. There, not all branches will need to compile on any given 
compiler invocation, though I am not sure that this is an important case 
(as usually every piece of code just targets a specific edition).
