Subject: Re: Class variable inside block of defining instance method

Ruby doesn't scope quite like that normally, but you can do it using
instance_eval and define_method:

def initialize(server1, server2)
  @echo = echo = IRC::Client.new(*server1)
  @listen = IRC::Client.new(*server2)
  @echo.instance_eval do
    define_method :message_received do |nick, channel, message, *args|
      if channel == "#Pre"
        echo.puts("PRIVMSG #{echo.channel} :#{message}")
      end
    end
  end
end

instance_eval has some quirks, and define_method methods are never as
fast as normal methods (since they have full block dispatch
semantics), but this should do what you need.
