Python

Futures and Streams, with zero allocation, because they are compiled, via macros, into an FSM
code sample:

  let requests = ParseStream::new(input);
  
  // For each request, run our service's `process` function to handle the request
  // and generate a response
  let responses = requests.and_then(|req| service.process(req));
  
  // Create a new future that'll write out each response to an `output` I/O object
  StreamWriter::new(responses, output)
