Expanding the capabilities of const fn is a tremendous achievement, years in the making. Congratulations to all involved (though of course there's much work yet to be done)! I especially appreciate that the syntax for const fn is "just" Rust, without being any sort of DSL or metalanguage, making it quite approachable and usable. The stabilization of the Pin API is also quite the achievement; the GitHub issue discussing it is one of the densest and most extensive threads I've seen: https://github.com/rust-lang/rust/issues/49150
