alt Hacker NewsAs someone who is "into" programming languages (and making toy implementations of them), I think some of the most important macros are along the lines of Rust/Haskells `derive/deriving` for quickly enabling serialization, printing etc. Using a language without such capability quickly becomes frustrating once you move to any kind of "real" task.
In any kind of real task, serialization is not the hard part.
If you can write a meta program for it, you can execute that in CI and spit out generated code and be done with it. This is a viable approach in any programming language that can print strings to files.
It’s not frustrating, but maybe it feels tacky. But then you shrug and move on to the real task at hand.
