This must be the most fun thing on my radar right now, because I got to it first thing this morning :)

  ; translate.arc
  (def translate (expr)
    (accum acc
      (translate-2 expr acc)))

  (def translate-2 (expr acc)
    (if (atom expr)
          (acc expr)
        (is car.expr 'suite)
          (do (acc 'suite)
              (let (suite-name . suite-body)  cdr.expr
                (acc suite-name)
                (translate-suite-body suite-body acc)))
        (is car.expr 'suite-w/setup)
          (do (acc 'suite-w/setup)
              (let (suite-name suite-setup . suite-body)  cdr.expr
                (acc suite-name)
                (acc suite-setup)
                (translate-suite-body suite-body acc)))
        'else
          (map acc expr)))

  (def translate-suite-body (suite-body acc)
    (if suite-body
      (if (acons car.suite-body)
        ; nested suite
        (let (nested-suite . rest) suite-body
          (acc (accum acc2
                  (translate-2 nested-suite acc2)))
          (translate-suite-body rest acc))
        ; test name must be atomic
        (let (test-name test-body . rest)  suite-body
          (acc `(test ,test-name ,test-body))
          (translate-suite-body rest acc)))))

  ; bootstrap tests for a test harness :)
  ; suite with tests
  (assert:iso '(suite a (test t1 b1) (test t2 b2))
              (translate '(suite a t1 b1 t2 b2)))

  ; suite with tests and nested suites
  (assert:iso '(suite a (test t1 b1) (suite s2 (test t3 b3)) (test t2 b2))
              (translate '(suite a t1 b1 (suite s2 t3 b3) t2 b2)))

  ; suite with setup and tests
  (assert:iso '(suite-w/setup a (x 1 y 2) (test t1 b1) (test t2 b2))
              (translate '(suite-w/setup a (x 1 y 2) t1 b1 t2 b2)))

  ; suite with setup and tests and nested suites
  (assert:iso '(suite-w/setup a (x 1 y 2) (test t1 b1) (suite s2 (test t3 b3)) (test t2 b2))
              (translate '(suite-w/setup a (x 1 y 2) t1 b1 (suite s2 t3 b3) t2 b2)))

  ; run
  (each f cdr.argv
    (prn f)
    (fromfile string.f
      (tofile (+ string.f ".2")
        (each expr (drain:read)
          (let out translate.expr
            (ppr out))))))
Run it like so:

  $ arc translate.arc *.t lib/*.t lib/tests/*
I haven't committed it anywhere yet because I'm not too happy with the state of Anarki's pretty-printer. Would you mind if I change the indentation style for suites and tests in Anarki? I was thinking something like this:

  (suite atom
    (test includes-int (assert-t (atom 3)))
    (test includes-float
      (assert-t (atom 3.14159)))
    (test includes-exact (assert-t (atom 3/16)))
    (test includes-symbol (assert-t (atom 'a)))
    (test includes-char (assert-t (atom #\a)))
    (test includes-string
      (assert-t (atom "hello")))
    (test includes-nil (assert-t (atom nil)))
    (test excludes-list
      (assert-nil (atom '(1 2 3))))
    (test excludes-table
      (assert-nil (atom (obj a 1 b 2))))
    (test excludes-tagged-types
      (assert-nil (atom (annotate 'foo 34)))))
..rather than this current output:

  (suite atom
         (test includes-int (assert-t (atom 3)))
         (test includes-float
               (assert-t (atom 3.14159)))
         (test includes-exact (assert-t (atom 3/16)))
         (test includes-symbol (assert-t (atom 'a)))
         (test includes-char (assert-t (atom #\a)))
         (test includes-string
               (assert-t (atom "hello")))
         (test includes-nil (assert-t (atom nil)))
         (test excludes-list
               (assert-nil (atom '(1 2 3))))
         (test excludes-table
               (assert-nil (atom (obj a 1 b 2))))
         (test excludes-tagged-types
               (assert-nil (atom (annotate 'foo 34)))))
