So now we can come back to our original subject - what is the added
value of Text_IO, then? What is the point of abstracting the notion of
text, if it "is in each other's head"? Shouldn't stream I/O be enough
and leave the rest to everybody's head in this case?

Of course it does. Cygwin is your best friend.

You shouldn't.

The only thing I can say now is that not only you don't use Unix, but
you also don't use plenty of software packages that exist on Windows.

This makes the end of stream indistinguishable from arbitrary delays.
Not a good idea. What about the stream of keystrokes? Is the stream
finished just because I'm thinking what to type next?

It is not a stream end, it is a communication error. Guess what - some
protocols are wiser than HTTP and can figure that out, which disproves
your universal "any" qualifier.


As in the majority of such discussion, we don't have a converging
thread and we're not likely to come to any conclusion either (and we
are long ago far away from the original problem, too).
Is it OK to suggest that we should somehow finish?
