Talking about the same thing as the article: hobby/learning languages. If you click the links to the author's projects you can see they have yet to finish a compiler or really even come close. Definitely not talking about sophisticated production-grade languages here; OP is trying to complete their first compiler at all. I think writing compilers is a really neat and useful learning project but you have to be smart about not biting off more than you can chew.

I would absolutely recommend not supporting incremental compilation or error recovery in your first compiler. Just stop everything at the first error. Save that for your second hobby compiler, or better yet, the first commercial compiler that you get paid to work on.
