But when I took a look one fatal problem leaped out at me: socket-port returns a "fresh binary input/output port". What is a binary input/output port? There is no such thing in R7RS. What you're talking about is a *pair* of ports: A binary input port and a binary output port. These are separate (disconnected) streams of bytes. I'm not talking ideal/clean design here. The Java Socket class has two separate methods: getInputStream and getOutputStream. Kawa I/O builds on Java I/O, which does not have "input/output streams". There is no clean simple way to implement socket-port in Kawa, and I have no plan to contort Kawa I/O to deal with this. -- --Per Bothner xxxxxx@bothner.com http://per.bothner.com/
