Re-thought Rack API

rack.rb

class Middleware
  # Processes a request before it reaches the application.
  # 
  # The middleware can change the flow of the request/response chain by:
  #  - Raising an exception, which will halt the process
  #  - Returning an instance of Response, which will go through the middleware layer
  # 
  # Returning any other value will not do anything.
  def process_request(request)
    # ...
  end

  def process_response(request, response)
    # ...
  end

  def process_exception(request, exception)
    # ...
  end
end

looks like java-servlets to me ;-)

Perhaps :-)

It would allow non-recursive middleware processing, e.g.

middlewares.each {|middleware| middleware.process_request(request) }
response = application.call(request)
middlewares.reverse.each {|middleware| middleware.process_response(request, response) }

This is overly simplified, but should alleviate some of the GC issues caused by Rack.
