Actually that illustrates the objection.  It's not the FILE object
that's the center of this process, it's the C compiler's read_a_line
function, which is part of the read_source_file_xxx group of
functions.  These may happen to use fopen, and fread or fgets to
actually physically retrieve in the input line, but they have to
maintain other stuff as well.  For example the line number so that you
can produce error messages.  Then the read_a_line function will
provide the higher levels of the compiler some way to associate a
particular point in the input stream with that data, so that a
meaningful error message can be produced.
