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).
