Perhaps.  But the beauty of the C and other approaches is that I don't
have to write the buffer explicitly, and thus have to debug it.  I *can*
read character by character if I want to, and often I do; socket
programming is a perfect example.  But the rest of the time, I don't
want to worry about it, and don't have to.

Perhaps you feel that Unbounded_String is an abomination, because `the
proper way' to do arbitrary length strings is to do it yourself?
