I see that SBCL's pretty-printer has its oddities, too -- the space before the "]" and a newline at one point... Anyway, `pp' prints arrays in pretty much the same way it prints lists, and I think this makes sense, and it pretty readable. (If a bit verbose.) So I'm closing this bug report as a "wontfix". -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
