while let Some(peek_ch) = chars.peek() && peek_ch.is_whitespace() {
chars.next();
}
Rust-analyzer is complaining with
`let` expressions in this position are unstable
see issue #53667 <https://github.com/rust-lang/rust/issues/53667> for more information```
Aren't let and while let chains stabilized?
When I run `cargo --version` I get `cargo 1.66.0 (d65d197ad 2022-11-15)`Also, followup question: How do I know what unstable feature to enable to allow this?

let chains are not stabilized; they nearly did but the stabilization was reverted due to bugs found late

if you are using nightly then the message will tell you which feature controls it. Stable compilers only tell you it's unstable. In this case it's let_chains
= help: add `#![feature(let_chains)]` to the crate attributes to enable
