Hi again,
I just had some doubts about the details of lexical-let for elisp, which
seem to be not answered by the document I linked to... Maybe you can
clarify these to me.
Especially, the question is about "what happens" when a lexical variable
is inside its scope again bound dynamically (say via let or a lambda
expression). Like in this example (I'm not sure if all my expected
outputs are right, please correct me as needed):
(defvar x 1)
(defun foo () x)
(lexical-let ((x 2))
x ; -> 2
(foo) ; -> 1
(setq x 3)
x ; -> 3
(foo) ; -> 1
(let ((x 4))
x ; -> 4?
(foo) ; -> 4
(setq x 5)
x ; -> 5
(foo) ; -> 5
) ; end the let
x ; -> 3?
(foo) ; -> 4
)
x ; -> 4
(foo) ; -> 4
So in this case all references to x in the lexical scope of the let are
to the dynamic value again, while the lexical is untouched and restored
after leaving the let?
Have a nice evening!
Daniel
