This might be a distracting aside, but could you comment on the idea 
that I think Stefan mentioned previously: that the native compiler could 
use not the original source files, but the byte-compiled *.elc files as 
the "source". By the time those are compiled, all the dependencies are 
resolved one way or another, right? So the user won't need to suffer the 
same kind of warnings again.

Do they contain the necessary information to do native-compile, and its 
various optimizations? If yes, are there any other difficulties 
associated with such an approach?
