rc"" instead of cr"" should get a clear diagnostic #140170
Description
Code
fn main() { rc"\n"; }Current output
error: prefix `rc` is unknown --> src/lib.rs:2:5 | 2 | rc"\n"; | ^^ unknown prefix | = note: prefixed identifiers and literals are reserved since Rust 2021 help: consider inserting whitespace here | 2 | rc "\n"; | + error: expected one of `!`, `.`, `::`, `;`, `?`, `{`, `}`, or an operator, found `"\n"` --> src/lib.rs:2:7 | 2 | rc"\n"; | ^^^^ expected one of 8 possible tokensDesired output
error: prefix `rc` is unknown help: consider using `cr` instead:Rationale and extra context
not sure whether the combination of c-string and raw string is common, but this seems like a plausible mistake if it is
