Not really.  It loads the files, and loading the files sets the
directory-local variables.  I don't think it is a good idea to use them
for byte compilation even though I have to admit that a directory-wide
setting of `lexical-binding' would seem less ugly than putting it in
every file manually.  But it sounds like a recipe for trouble.
