I never use it for regex, because when using CL, I tend to be authoring the regex from scratch. But I found it elegant and thought it might be useful to interpret someone else's hairy regex. But the reason I mentioned it, was because I thought it might be more useful to me for FORMAT... just because decades of Perl 5 taught me regex really well, but I don't get to use CL's FORMAT syntax every week. ;-)

Your further points are well taken.
