That's a good argument for keeping the set of languages limited. But it doesn't necessarily have to be just one.

  It never is. Even ancient unix had shell and (maybe more to your point) yacc. Yacc still generates C files, but that's more of an implementation detail. The C _interop_ is key.

      Well, of course! I was talking about why yacc is a second language for (early and contemporary) unix. Its C interop for (early and contemporary) unix is what I was stressing.

        Ah ok, sorry for being pedantic. You are fully right.
