If you follow the C++ newsgroups, you'll soon see that the same sort of
people who are confused about "erroneous" are confused about "undefined"
as well. They tend to mix it up with "implementation-defined", and get
quite indignant when no one offers them any sympathy :-)

For waht it's worth, I like "erroneous" better - it conveys to me the
sense that I have done something wrong, whereas "undefined" conveys to
me the sense that the language has forgotten something.
