Yes. It was not-so-great morning idea.

But even today you have to mark the end somehow, to distinguish it
from "not done yet, more could be coming". The equivalent is typing ^D
into a UNIX terminal (or ^Z on Windows).

My interns told me that they remember EOF as special object only from high school when they had to study Pascal. I guess, in 5 years students won't understand how one can write an EOF. (and schools will finally replace Pascal with Python)

Kind regards, Yuriy.
