As you wish!

I'm currently not supporting named-let.  Meanwhile, my in-flight work
for this morning:

let:
  x = 3,
  y = 2
 in:
  +(x, y)

let*: x = 3, y = x in: +(x, y)

letrec: even = ;; perversely written as a one-liner
               fun: (n) in: if: zero?(n) true else: odd?(sub1(n)),
        odd = fun: (n) in:
                if: zero?(n)
                  false
                else:
                  odd?(sub1(n))
 in: list(odd?(10), even?(10))

Note the new indentation rule, described in the manifesto.
