Whereas ACL being the commercial, we don't please the customer by
nagging him, easygoing dude that he is, lets me write very useful (to
me) logical pathname definitions that then blow up spectacularly when
the language lawyer SBCL gets her hands on them....

If you use multiple lisp implementations, I'm now convinced that using
logical pathnames is tantamount to taking a big pile of hours, putting
them in an ashtray, and setting fire to them.
