Can't you just use:

ActionController::Routing::Routes.draw do |map|
  map.good 'good', :controller => 'good', :conditions => {:method => :get}
  map.bad 'bad', :controller => 'bad'
  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
end

Does it make any sense to add a condition that matches every case?

the documentation states "Takes a hash of #{action} => #{method}, where method is :get/:post/:put/:delete, an array of any of the previous, or :any if the method does not matter."

i'm expecting consistent behavior, one way or the other.

% grep -R ':any' r*
resources.rb:    #   an array of any of the previous, or <tt>:any</tt> if the method does not matter.
resources.rb:    #   map.resources :messages, :new => { :new => :any, :preview => :post }
resources.rb:          options[:conditions][:method] = method unless method == :any
routing/route.rb:          "%-6s %-40s %s" % [(conditions[:method] || :any).to_s.upcase, segs, requirements.inspect]
routing.rb:  #   <tt>:get</tt>, <tt>:put</tt>, <tt>:delete</tt> and <tt>:any</tt>. The default value is <tt>:any</tt>,
routing.rb:  #   <tt>:any</tt> means that any method can access the route.

This seems does seem to be broken.

Works for resources (:collection => {:test => :any}) but not for named paths.

Apply cleanly to current stable.

+1 I verified this patched worked for me in a mini app, as well as the tests passed.

+1 verified. Applies cleanly to current stable & master.

Tests pass for stable, and two tests fail on master. I do not believe they're related -- they're dealing w/ the textilize method.

If you need a quick substitute, passing in nil in place of :any works as follows:
:conditions => {:method => nil}
