Yes, that does look inconsistent with the documentation. I use DEFPARAMETER if I need such a variable.

Perhaps that line of documentation dates from before Vladimir implemented lexical scoping.

By the way, Vladimir is traveling for a few months and most changes will probably have to wait until he is back.

Also,

$ cat foo.lisp
(let ((s-a))
(+ s-a 42)
(chain s-a (append-child foo)))

"(function () {

Which is against documentation "Top-level LET and LET* forms will create new global variables, or overwrite the values of already existing global variables with the same name."

Please comment
