Thanks. > I'm not sure what "new names for variables" means here. All the examples I could find were of the template (when-let ((name1 scalar1) (name2 scalar2) ...) where presumably the `scalar`s were standins for existing named bindings. Same for `if-let`. I wasn't awake enough to contemplate that the `scalar`s above could probably be arbitrary expressions. But skimming your blog post again, I do see this example about half-way through: (let* ((name (read-string)) (length (length name))) ; ... )
