According to: <http://www.gnu.org/software/guile/manual/html_node/Adding-or-Setting-Alist-Entries.html> "The only safe way to update an association list variable when adding or replacing an entry like this is to set! the variable to the returned value" You cannot just assoc-set! an associative list. So a procedure with setter does not help in that case (unless I've misunderstood something).
