If it were up to me to design curricula for CS, I'd do the entire thing in Ada, with the exceptions of "Data-Structures & Algorithms" being in Lisp and "Machine Architecture" in Forth — both of these classes would have a "Compilers & Interpreters" prerequisite where they would be provided the specification-files for Forth and Lisp interpreters/compilers which the students would implement, and that is what they would use in the aforementioned classes — not only would having the curriculum in these less-popular languages help emphasize that the important part is the underlying-theory (rather than hyped-up language-of-the-month), but making its prerequisites actually matter and introducing an element of software-maintenance would do a lot to produce good graduates.
