there are other options:
- having `llet' and `dlet' as "main" forms and `let' as an alias to one
of them (`dlet' by default); then (use-lexical-binding) would just do
(defalias 'let 'llet)
- adding CL `special' declarations, and making `let' a macro,
like I have in CLOCC/CLLIB/elisp.lisp:
(defmacro el::let ((&rest vars) &rest forms)
"Emacs-Lisp version of `let' (everything special)."
`(let ,vars (declare (special ,@(mapcar #'from-list vars))) ,@forms))
this has the advantage of ability to mix lexical and dynamic
bindings.
I like the latter option best.
