Which of my three statements are you referring to? Your use of vague
words like "that" doesn't help.

What is "streaming I/O"? stdin and stdout are streaming I/O too. Do you
consider them non-Phobos?

I read the above multiple times. Unfortunately I can't understand more
than what I already knew.
Let me get back to my three statements:
1) Streams are gone from D. Since with "streams", I can only possibly
mean what is already in D, I mean those streams are gone from D. I
shouldn't need to disclaim that some module in the future may be related
to streams.
2) Streams that are currently present in D are deprecated in favor of a
new interface that will use ranges, or be ranges.
3) The seminal paper that I linked above is it.
