Using let-bound var inside pcase conditions

[Kaushal Modi]

Hi,

I am trying to set the conditions in a pcase to variables, but cannot get
it working (See below dummy code).

Can you help fix the second message form below?

;; -*- lexical-binding: t; -*-

(defun pcase-test (var)
  (let ((one 1)
        (two 2))

    (message "(good) Value is %s." (pcase var
                                     (`nil "nil")
                                     (1 "one")
                                     (2 "two")
                                     (_ "none of the expected")))
    (message "(bad)  Value is %s." (pcase var
                                     (`nil "nil")
                                     (`,one "one")
                                     (`,two "two")
                                     (_ "none of the expected")))))
(pcase-test nil)
(pcase-test 1)
(pcase-test 2)
(pcase-test 3)
