Sure! Compilers was one of my favorite classes, but it was also one elective among many. There's other stuff I took here that was ommitted: courses on tbe completeness of first-order logic, Gödel's incompleteness theorem, natural language processing, graph theory, abstract algebra, numerical analysis... there's also a lot of applied/engineering math stuff in there (the latter two semesters of calculus, stats) which I took because I wanted to but was not at all required by my CS degree. Not all CS degrees look alike.
