Input streams are a purely functional "lazy list of bytes" abstraction. Output streams are just a duplicate set of functions that do more-or-less the same as ports, as far as I can tell. Output streams can be "translated" but is there any reason you can't have a translated output port? Useless symmetry is still useless, especially if it just ends up being needless redundancy. A true output stream api would work on "sequence of bytes" too. The output operation would be something like this: (output-byte stream byte) Does not modify either argument. Creates a new stream, which is a copy of the 'stream' followed by the 'byte'. (Lazy copying can be used in practice.) -- --Per Bothner per@xxxxxxxxxxx http://per.bothner.com/
