Eric Huss 4e9c91f0ec Place `rustc` behavior in a side note. 
Generally the reference tries to stay focused on the language, and only
provide implementation notes as side-information.

Matthew Woodcraft e364b6c6f9 lexical structure: move the description of shebang-removal 
This takes place after CRLF normalization.

It's better not to list the shebang in a Lexer block, as it isn't a token that
can be fed to a macro.

Matthew Woodcraft 5f512692d3 lexical structure: move the description of BOM-removal 
This takes place at the same time as CRLF normalisation.

It's better not to list it in a Lexer block, as it isn't a token that can be
fed to a macro.
 2024-01-28 18:42:40 +00:00
Matthew Woodcraft fa56fdba0e Lexical structure: move the description of CRLF normalization 
We now say that CRLF normalization happens as a separate pass before
tokenization.

Document object unsafety of async-fn-in-trait
 2023-12-10 16:16:17 +00:00
Kevin Reid 46ed38d89d Document object unsafety of async-fn-in-trait 
`async fn` in traits, and return-position `impl Trait` in traits, were stabilized by <https://github.com/rust-lang/rust/pull/115822>. The object-safety error E0038 points to the Reference, so the Reference should mention this new criterion.

Reference wildcard patterns from underscore expr 
These appear in nearly identical locations in source code and have subtly different semantics, so cross link them.
