No -- sorry; each such option requires Lisp->C translation support.
Currently in CL def-clm-struct piggybacks on the existing array
support. To add specialized print functions, it needs to register a
new type for the struct, then add an entry to mus_print_object. You
could get the same effect by defining a macro that does the printing
you want (but, of course, a value like 'baz isn't going to work -- I
don't try to support symbols in any version of the run macro).
(def-clm-struct foo (bar 1.0))
(defmacro print-foo (f) `(clm-print "<hello: ~A>" (foo-bar ,f)))
