Indeed. I first wrote an enum-to-string macro back in the late 80s in C, and again in the late 90s for C++. And here we are in 2022... still writing enum-to-string macros and the like.
I've needed linked list more often than enum to string over my 20+ years in industry. (both combined is less than a handful) This is mostly about what problems I've had to work on.
I think linked list taught me more useful skills than enum to string, even though I had to figure out the later on my own. Which is the important part of education, does learning things directly or indirectly help you more in the long run.
