I'm trying to find a simple way to create a plugin architecture. Preferably: as soon as the class is inherited, it's added to the plugin manager. I'm thinking that PluginManager is in the biggest need of a cleanup.

module PluginManager
  @plugins = []
  
  def self.<<(plugin)
    @plugins << plugin
  end
  
  def self.plugins
    @plugins
  end
end

class Plugin
  def self.inherited(klass)
    PluginManager << klass.new
  end
end

class Whatever < Plugin
  
end

PluginManager.plugins # => [#<Whatever:0x28564>]

require 'singleton'

class PluginManager < Array
  include Singleton
end

class Plugin
  def self.inherited(klass)
    PluginManager.instance << klass.new
  end
end

@Tj Holowaychuk, I don't think you understand what I'm getting at...
