It is still a great learning exercise IMO. Knowing which features are good/familiar to use, but difficult to implement, lets you explore other avenues, like news_to_me and the backslash for lambda [1].

For me, for example, I was gonna go with async/await in my toy language, but didn't like the implementation and decided to explore a monad-like direction.

I can see this learning exercise applying to other things, only it takes a lot of time and commitment. So far I've also learned a lot on other projects that I was able to carry out more fully. But everyone has their thing.
