[slime-devel] Indentation question

[Nikodemus Siivola]

I have a nasty habit of writing macros with multiple keyword clauses
in them--like this:

(deffoo foo (stuff)
  (:bar (a b)
    (cons a b))
  (:zot (a b c)
    (fii a b c))
  (:default
    42)
  (:error
    (crap)))

which of course tend to indent terribly

(deffoo foo (stuff)
  (:bar (a b)
        (cons a b))
  (:zot (a b c)
        (fii a b c))
  (:default
      42)
  (:error
   (crap)))

I've occasionally added special indentation rules for these things in
.emacs, but that's no fun at all. I've also sometimes used non-keyword
symbols and added global definitions which tell slime how to indent
things:

 (defmacro bar (lambda-list &body body)
   (error "oops, not in DEFFOO"))

None of these is really satisfactory: hacking .emacs means users of a
library that has macros with this style don't get the correct
indentation in Slime out of the box. Using non-keyword symbols makes
the code harder to read. (Keywords make it obvious that those are
clauses or options of some sort.)

Can someone suggest something better?
