404 when using Rack::Builder

[EppO]

Does reel-rack support Rack::Builder in the config.ru ?
When I try to use map inside a Rack::Builder.new block, I get only 404 responses.

I tried with:

require_relative "hello"
require_relative "world"
require_relative "request"

app = Rack::Builder.new do
  #use Request

  map '/' do
    run lambda { [ 200, {"Content-Type" => "text/html"}, "What did u expect ?" ] }
  end

  map '/hello' do
    run Hello.new
  end

  map '/world' do
    run World.new
  end
end

run app

all the URLs above (/, /hello, /world) sends back 404

I tried couple of other things like.
This doesn't work either:

app = Rack::URLMap.new('/hello' => Hello.new,
                       '/'      => lambda { |env| [200, {'Content-Type' => 'text/plain'}, ' What did u expect ?'] })
run app

What works on the other side is when I don't use map inside the Rack::Builder.new block:

app = Rack::Builder.new do
  #use Request

  run Hello.new
end

run app

So reel-rack can use a Rack::Builder app but doesn't seem to be able to get map routes correctly.

Wonder if this is related to our use of Rack::MockRequest

Is there any workaround to be able to use different Rack endpoints ?

Not that I know of. Perhaps we're using Rack incorrectly here?
