Hello,

Is the following in Emacs a expected behavior of macro?

    (defmacro m1 (v)
      (let ((len (length (eval v))))
        `(quote ,len)))
         => m1

    (m1 '(1 2 3))
         => 3

    (setq v1 '(1 2 3))
         => (1 2 3)

    (m1 v1)
         => 3

    (setq v v1)
         => (1 2 3)

    (m1 v)
         => error: (wrong-type-argument sequencep v)

Thanks.

Regards,
Guanpeng Xu
