I think the only reason for this is an implementation detail (lexical-binding is parsed by other code than the other file-local variables). It would be great to make it consistent with other variables so that the user doesn't need to care about the difference.

A few years ago, we said (IIUC) it was desirable: http://debbugs.gnu.org/10605 http://lists.gnu.org/archive/html/emacs-devel/2012-01/msg00543.html Or have speed-ups in uncompiled code shifted the balance?

The check for "coding:" is a misdesign, indeed. I think we should use some utf-8 tell-tale sign at the beginning of *.el files to eliminate the need to check for "coding:" (and to go through load-with-code-conversion) in the normal case. It could be a utf-8 BOM or something like that. Ideally we could give extra meaning to this marker so it not only means "uses utf-8" but also "uses lexical-scoping", so that we can have a future where we don't need to add "lexical-binding:t" to every file.

The check for "coding:" is a misdesign, indeed.=C2=A0 I think we = should use
some utf-8 tell-tale sign at the beginning of *.el files to eliminate
