Rails 3: new namespace inside nested resource?

Hi,

Is there a way to use namespaces inside nested resources? For example,
I have:

resources :users do
  resources :tags
end

and I'd like to place the tags controller inside controllers/users,
with the equivalent for templates.

If I try this:

resources :users do
  namespace :users do
    resources :tags
  end
end

I'll get redundant route names:

users_user_tags, users_user_utag, etc

This doesn't work either:

resources :users do
  resources :tags, :module => :users
end

And yet, nested resources seem like a good candidate to use
namespaces, to better organize files and avoid name conflicts.

Thanks,
