And I wouldn't expect that in a programming concepts course.  But, if
you're going to (for example) say that, "preincrement and postincrement
work exactly as in C," you've got to realize that there's a chance a
student will know that the i++ + ++i is undefined and expect it to be
undefined in the language you're talking about.  That's the problem with
using shorthand phrases like "exactly in <X>" without the "except ..."
