Subject: bug#20640: 24.5; lexical-binding should work like a normal file-local variable
Date: Sun, 24 May 2015 12:19:34 +0200

The manual
(https://www.gnu.org/software/emacs/manual/html_node/elisp/Using-Lexical-Binding.html)
says about `lexical-binding':

   Note that unlike other such variables, this one must be set in the
   first line of a file.

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.
