One additional note: the provided code for that course is (or was a decade+ ago!) either C++ or Java, but the tests and test scaffolding are fairly straightforward. I opted to translate into Go as I went, which meant: - a lot more work/time - slower progress - no “if you fill in this missing piece, we’ve provided the rest so your compiler will work end-to-end” - an annoying amount of trying to print ASTs exactly like the C++/Java code for validation purposes But I got to use Go instead of those other languages! ;-)
