Assuming we don't want to flip the default for 'lexical-binding' just yet, would it be possible to warn the user any time they load interpreted code that uses dynamic binding? We could potentially do the same for .elc files that were implicitly compiled with dynamic binding (i.e. without a "lexical-binding: nil" cookie), but in my opinion it would suffice to warn users when they recompile that file. There's nothing I'm aware of that makes the dynamically-bound .elc *wrong*; it's just not preferred, and one day, you might get a lexically-bound .elc instead. Or we could just flip the default now. - Jim
