BUT back on the thread's topic, since i started programming in Rust, the only time i've felt it was hard to wrap my head around the compiler's output was with complex async programming. Otherwise, every single time i felt like a simple text editor was more than enough with rustc's output to understand what's going on, because in Rust everything is very explicit and statically typed with clear lifetimes, and the compiler has very helpful error messages often including suggestions on how to fix the error.

For me, everything (non-async) Rust is a clear win in terms of understandability/hackability, compared to all other languages i've tried before (admittedly not a lot of them). I think complex IDE tooling can ease the pain, but proper language design can help prevent the disease in the first place.

EDIT: i should add, since i started programming in Rust, i've only once or twice seen a runtime panic (due to array indexing error on my side). Otherwise, literally all of the bugs i had written were caught by the compiler before the program ran. For me it was a huge win to spend one more hour to please the compiler in exchange for spending days less debugging stuff afterwards.
