 It might be that I don't understand something, but I wrote this piece of
 code yesterday:

 {{{
 # admin.py
 def action(fun):
     def immediately(modeladmin, request, queryset):
         result = fun(queryset)
         if result:
             modeladmin.message_user(request, result)
     immediately.short_description = fun.short_description + " (now)"
     def queue(modeladmin, request, queryset):
         fun.delay(queryset)
         modeladmin.message_user(request, "Added to the queue.")
     queue.short_description = fun.short_description + " (add to the
 queue)"
     return immediately, queue

 class CompanyAdmin(admin.ModelAdmin):
     actions = (*action(telephone), *action(mail))
 # (...)
 }}}

 And only functions generated by the first call to action() get added. (In
 the case above two actions from "telephone" only; when reversed, from
 "mail" only).

 I suspect that Django might detect them as duplicates.
