This is really nice - exactly what I'd like to see in the I/O library.
The trick is making it perform well, though... but I'm sure that's your
main focus too.
Still, I'm not sure that putting both input and output streams in the
same type is the right thing, I seem to remember a lot of things being
simpler with them separate.
