 {{{

 The similar warning can watch TCPServer/TCPSocket/UDPSocket.
 {{{
 macruby -r socket -e "TCPServer.open('localhost'){|f| p f}"
 unknown: warning: TCPServer::new() does not take block; use
 TCPServer::open() instead

 macruby -r socket -e "TCPSocket.open('localhost', 80){|f| p f}"
 unknown: warning: TCPSocket::new() does not take block; use
 TCPSocket::open() instead
 -e:1:in `<main>': Connection refused - connect(2) (Errno::ECONNREFUSED)

 macruby -r socket -e "UDPSocket.open(){|f| p f}"
 unknown: warning: UDPSocket::new() does not take block; use
 UDPSocket::open() instead
 #<UDPSocket:0x2000c59c0>
