lisp_file_lexically_bound_p does not handle local variables lists. This
will make eval-buffer ignore the file-local value of lexical-binding if
it is specified in such a list.
Recipe: emacs -q, C-x b *scratch* RET, insert the following snippet, M-x
eval-buffer RET, M-: (rms) RET.
(defun rms ()
(let ((emacs 'vim-tiny))
(lambda ())))
;; Local Variables:
;; lexical-binding: t
;; End:

That's a known limitation, which we decided to keep since supporting
lexical-binding settings at the end of the file would force the
interpreter to read the whole file before starting interpreting.

Thanks for you answer. Is this limitation mentioned in the
documentation? If so, in which node?

In the doc string of the variable lexical-binding, in the NEWS file, and
in the "Using Lexical Binding" node of the elisp manual.
