On: When O3 is 2x slower than O2

I dislike macros for that reason when reading code on GitHub or Docs.rs, but Rust was kind of made to be used with an IDE (or LSP).

That is poor practice IMO. The simple reality of the world is that not everyone uses such tools. Designing a language with the expectation they will is deliberately ignoring the needs of some users.

IDEs were invented by a mix of XEROX PARC, Symbolics, TI efforts into graphical workstations development, we have moved beyond the point of refusal to adopt modern tooling.
