Cool! Another stack frame is in the process of being removed for async Rust. This will lead to even better diagnostics!https://github.com/rust-lang/rust/pull/70831 …
That's a great question! I don't know really. I'm not even sure "always inline", well, always inlines. I believe DWARF allows expanding stack traces to be more meaningful, so even if something is compiled down it will show up. But not an expert so can't tell you for sure.
