Note that the regrets were minor. :-)
The problem is that these are almost never used in real programs; real
programs use sys.stdin.readline() so they can properly handle EOF.
But their main use, teaching Python to beginners without having to
expose the whole language first, requires either that they are built
in or that the teacher sets up a special environment for their
students. For the latter, a PYTHONSTARTUP variable pointing to a file
with teachers' additions does nicely, but requires a level of control
over the student's environment that's not always realistic.
(Especially not when the student is teaching herself. :-)
Perhaps a special module of teacher's helpers could be devised, and a
special Python invocation to include that automatically?
