One of the main advantages of Simple streams is that they do not require a call through a generic function to do things like read-char, write-byte, etc. Its not that Gray streams cant do these things, its just that the interface is somewhat heavy. > I'm guessing at the current stage the Simple Streams approach would be > more useful, and later on the more abstract objects will become > interesting. I tend to agree. I ported the SBCL Gray streams code over to GCL this morning in the form of a user library (that is, its not redefining CL functions or sub-classing CL's stream type -- its portable code similar to Corman Lisps implementation). Next will be to attempt the same with SBCL's Simple stream implementation. Once both portable versions are running I can look at how they can be embedded in GCL so as to take advantage of implementation specifics. Hopefully a lot of the details, pros/cons, etc, will become clear by taking that approach.
