deftem

[Kerrigan29a]

I'm trying to run this code from anarki

(= templates2* (table))

(mac deftem2 (tem . fields)
  (withs (name (carif tem) includes (if (acons tem) (cdr tem)))
    `(= (templates2* ',name)
        (+ (mappend templates2* ',(rev includes))
           (list ,@(map (fn ((k v)) `(list ',k (fn () ,v)))
                        (pair fields)))))))

(deftem2 point2d x y)

and I'm getting

Syntax error : (fn ((k v)) (cons (quote list) (cons (cons (quote quote) (cons k (quote nil))) (cons (cons (quote fn) (cons (quote nil) (cons v (quote nil)))) (quote nil)))))
error in expression:
    (deftem2 point2d x y)

But if I execute it in Try ARC it runs well

           (list ,@(map (fn ((k v)) `(list ',k (fn () ,v)))
                        (pair fields)))))))
