Subject: access variables inside a block ...

I'm playing with the class TcpServer from the
package ldap-server.

There is an interesting way for me of running a tcp server.

-----------------------------

t = GAME::Server.tcpserver(:port=>1110, :nodelay=>true) do
     print "+OK I am a fake POP3 server\r\n"
     while line = gets
       case line
       when /^quit/i
         break
       else
         print "-ERR I don't understand #{line}"
       end
     end
     print "+OK bye\r\n"
   end
   t.join
end

----------------------------

inside the GAME:Server.tcpserver it looks like

----------------------------

   def self.tcpserver(opt, &blk)
     server = TCPServer.new(opt[:bindaddr] || "0.0.0.0", opt[:port])
     server.listen(opt[:listen]) if opt[:listen]

     Thread.new do
       while true
         begin
           session = server.accept
           Thread.new(session) do |s|
              s.instance_eval(&blk)
           end
         rescue Interrupt
           server.close if server and not server.closed?
           break
         end
       end
     end
   end

------------------------------

Now, how can I get access to the "session" variables.
I need some information from TCP inside the block.
But I couldn't find out how.

Thanks for reading the mail and maybe an answer :)
