Actually the more general issue of undefined is pretty language
independent, and indeed it it important not to misuse the word
illegal for this purpose. The mention of courts is really besides
the point. The important point is to stick to the precise
terminology of the appropriate standard when talking about
incorrect programs, whatever the language.
