I found this better structure to be 'any' which allows me to iterate 
over a list of mappings like this:

     (property-path
      (any
       (lambda (type)
         (if (memq (car type) types)
             (let ((result (cdr type)))
               (if (procedure? result)
                   (result)
                   result))
             #f))
       `((context-specification . ,parse-context-spec)
         (key-change-event . (Staff KeySignature))
         (mark-event . (Score RehearsalMark))
         (ottava-music . (Staff OttavaBracket))
         (tempo-change-event . (Score MetronomeMark))
         (time-signature-music . (Staff TimeSignature)))
       ))

(within a let-block).
However, this leaves open my question of where and how to determine 
which events/grobs I will have to support in this alist.

Any suggestions?
Thanks
