> Compilers make it very clear how all those seemingly disparate topics apply in real non-trivial systems. Combined with a proper OS class, it's the first time a student can truly understand all the levels of abstraction from the language to the logic gate. And it also helps to recognize and solve parsing problems. How many programs end-up containing a parser, even if rudimentary, to read non-trivial input of perform validation? No, you can't use regex for that...
