What's the problem with Clojure?:

    (defmacro when
	  "Evaluates test. If logical true, evaluates body in an implicit do."
	  {:added "1.0"}
	  [test & body]
	  (list 'if test (cons 'do body)))

Moreover, what's the problem with μLithp?

    l.eval [:label, :second, [:quote, [:lambda, [:x],   [:car, [:cdr, :x]]]]]

    l.eval [:second, [:quote, [1, 2, 3]]]

Seems list-y enough for me. I have a feeling that you didn't actually read the article.
