Excuse me for not following the thread and perhaps not understanding what
you say here. Are you saying that if `lexical-binding' is non-nil then
a function parameter whose name is the same as a dynamically scoped
variable is "not allowed" or does not refer to that variable?
That would be counter to how Common Lisp works, and I thought (and I hope)
that our aim was (is) to use the way Common Lisp marries lexical and
dynamic binding as our model.
In Common Lisp, a variable declared to be "special" (dynamically scoped)
can be used as a formal parameter to a function. See, for example,
http://www.ai.mit.edu/projects/iiip/doc/CommonLISP/HyperSpec/Body/dec_special.html
Again, sorry for the noise if I misunderstand. If not, please clarify.
Thx.
