# in a child process (relaying the value back up a pipe) and doing the

Inspired by @JEG2's talk at Rubyconf... Any ruby object, as a webapp! 'Cause we can. :-)
View webapp.rb
require 'rubygems'
require 'rack'
class Object
def webapp
class << self
define_method :call do |env|
func, *attrs = env['PATH_INFO'].split('/').reject(&:empty?)
[200, {}, send(func, *attrs)]
end
View itr.rb
class Metaclass
include Enumerable
def initialize obj
@obj = obj
end
def each
return enum_for(:each) unless block_given?
x = meta_for @obj
