the latest Slime (both HEAD & FAIRLY-STABLE) does not load for me due to failed asserts that check the equality cited in the subject.
apparently #'pprint-logical-block in CMUCL 18e does not work the way swank.lisp thinks it works. or something.
I've worked around this by making #'test-print-arglist be:
(defun test-print-arglist (list string) (equal (read-from-string (print-arglist-to-string list)) (read-from-string string)))
perhaps it will break something; so far it does not.
