Feature Request: Ability to Tweak "/l" in mode-name

[T.V Raman]

At present the "/l" vs "/d" for lexical vs dynamic scoping is
hard-wired in the definition of emacs-lisp-mode; Could we make this
configurable?

(define-derived-mode emacs-lisp-mode lisp-data-mode
  `("ELisp"
    (lexical-binding (:propertize "/l"
                      help-echo "Using lexical-binding mode")
                     (:propertize "/d"
                      help-echo "Using old dynamic scoping mode\n\
mouse-1: Enable lexical-binding mode"
		      face warning

Do we offer customization of the mode lighter in any other modes?

You can always customize any part of the mode line directly, by
changing mode-line-format or its portions, so I'm unsure why we would
need yet another knob, and in this specific case in particular.

Some modes expose the mode lighter as a user option,
e.g. flymake-mode-line-lighter.  I suspect fewer do so in emacs.git than
in the wider ecosystem.

FWIW I use delight from GNU ELPA for this purpose, e.g.:

  (delight
   '((emacs-lisp-mode "(ε)" :major)
     (lisp-interaction-mode "(ι)" :major)))

Your solution works for me, though at some nit-level, Emacs
hard-wiring the "/l" and "/d" is likely going to make it harder to
internationalize -- but that is the least of my or emacs' problems:-)

Actually looking closer at this, it doesn't quite solve my problem, in
that it wont then let me know if it's using lexical or dynamic
scoping.

You can reproduce similar logic as that of emacs-lisp-mode's lighter
using Delight.  My example was just an excerpt from my configuration,
where I intentionally omit the lexical-binding information.

OK.
I made my life easier by setting major-mode as I wished in
emacs-lisp-mode-hook
