I think I disagree. Buffering should be the job of the OS and/or
standard libraries. Not every program.
I'm not sure why reading a file character-by-character is "C-like".
It seems like the natural way to write lots of programs, in any
language. The underlying language and OS should ensure that it can be
done efficiently (by making the "give-me-a-char" routine read from a
buffer whenever appropriate).
