I recently came across some unusual behaviour in MCL...
I defined a function which similar to the following:
(defun test (arg)
(let ((list1 '(nil nil)))
(push arg (second list1))
The first time 'test is called, the behaviour is as expected:
(test 1) ;=> (nil (1))
The second time however is unusual:
(test 2) ;=> (nil (2 1))
The result grows with each sucessive call. I can't see how this happens -
I would assume the scope of list1 was within the 'let. And certainly it is
not global as is suggested by thsi result.
