Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(msg, *args, &block) ⇒ Object

the use of singleton_class is making serialization hard! def initialize app, defaults

super
singleton_class.module_eval do
  defaults.each{ |(key, value)|
    define_method(key) do |env|
      if value.respond_to?(:call)
        value.call
      else
        value
      end
    end
  }
end

end
