I'm still awfully skeptical that you can get even close to understanding all the template, lookup, lifetime, lambda, exception and initialization rules in a semester (I assume that CS students are almost never this deep into C++ at that point). Not to speak of actually implementing all of it.

I'd be curious where these classes draw the line. Do you happen to have a syllabus or so? I don't doubt you can implement a meaningful portion of C++ in a semester, but converting 500 pages of standardese into code within as many hours seems like an impossible goal for a class to me.
