In contrast to ACL, GCL, and MCL, CMU Lisp and CLISP require
pathname strings to have a trailing slash, "/tmp/". Alternatively, you can use
MAKE-PATHNAME; use the list form:
(make-pathname :directory '(:absolute "tmp"))
But you make a point: the CL ANS says that string arguments to :directory
should be automatically be converted to (:absolute string), so
I will change this. Thanks.
