Re: "What are you going to do about..."

Well, READ and the :TYI operation do something other than returning the
end-of-file character at end of file.  Nobody said every input function
must return the end-of-file character when they get to the end; they
could return NIL, signal a condition, or anything they want.  That
doesn't mean there shouldn't be and end-of-file character; it just means
that Lisp input functions are not all the same in their handling of
end-of-file, which is already true in Maclisp and can't be changed.
