alt Hacker NewsIt's relatively common is university CS courses to build a compiler after the basic intro and architecture courses. It's one of the simpler projects (yes, really, compilers are rather simple, optimization is the hard part) that involves a lot high-level concepts and exposes a lot of the thought behind things otherwise obscure. A compiler for a simple 4-function calculator is enough to start with, then higher-level constructs can be added easily while introducing them.
In my university, compilers were a third-year course. And they're anything but simple - even the most well solved part of them, parsing, used to be a research-level problem until fairly recently. To build even a simple non-optimizing compiler you have to understand a whole lot of other fundamentals, such as various data structures, that are much, much harder to understand in assembler then in any higher level language, even C.
