+4. Alpha-conversion
+===================
+;; In lexical binding mode alpha-conversion works:
+;; https://en.wikipedia.org/wiki/Lambda_calculus#%CE%B1-conversion
+;; Try:
+
+(setq b 3)
+(defun getb () b)

+;; In lexical binding mode the 4-line `list' sexp returns a list
+;; of two identical lists. These two `let' sexps are equivalent:
+;;
+;;   (let ((a 2)) (list a (getb)))
+;;   (let ((b 2)) (list b (getb)))
+;;
+;; and the choice of `a' or `b' for the name of the variable
+;; doesn't matter. In dynamic binding mode the `b' of the
+;; `(let ((b ...)) ...)' is seen by the (getb), and it shadows
+;; the global `b'.
