Comment:

 As noted in
 [http://www.lispworks.com/documentation/HyperSpec/Body/03_dae.htm the
 CLHS], the use of &AUX is equivalent to putting the forms in a LET*
 binding, so as a workaround for the original problem with RESTAS replace

 {{{
 (defmethod submodule-routes ((submodule submodule)
                              &aux (decorators (submodule-decorators
 submodule)))
   (mapcar (lambda (route)
             (apply-decorators route decorators))
           (module-routes (submodule-module submodule) submodule)))
 }}}

 with

 {{{
 (defmethod submodule-routes ((submodule submodule))
   (let* ((decorators (submodule-decorators submodule))))
     (mapcar (lambda (route)
               (apply-decorators route decorators))
             (module-routes (submodule-module submodule) submodule)))
 }}}
