What I got was:

  - pointers to bitfields
  - checked bitshifts
  - small ints like u4
  - imperative array initialization blocks
  - test code blocks
  - equivalent of debugger; keyword from js
  - some vague stuff about being able to do at compile time

The rest is pretty generic

I had to dig farther on the compile time execution stuff. It's actually pretty cool-looking. Recommend digging into it. I don't know that it's a killer enough feature to draw me away from Rust's guarantees, but it is interesting.

It is difficult to overstate how useful compile-time execution is in practice. I can't imagine using a systems language without it now. The term "modern C++" largely denotes when compile-time execution was added to that language.

I would love to see Rust get compile-time execution that is as capable as Zig or C++20.

Isn't that just macros which are way more powerful than what Zig or C++20 offer?

Can you give examples? Const functions are pretty capable in Rust already.
