I don't know the guile internal (yet), but after looking around
(language tree-il) and (language ecmascript base) it seems `new-object'
want a list of pairs instead a list of lists.  I changed the above code
to

       `(apply ,(@implv new-object)
               ,@(map (lambda (x)
                        (pmatch x
                                ((,prop ,val)
                                 (-> (apply (-> (primitive 'cons))
                                            (-> (const prop))
                                            (comp val e))))
                                (else
                                 (error "bad prop-val pair" x))))
                      args)))

and it works.

Hope this helps you to diagnose the problem.

Cheers,
Kanru
