//[edition2018] edition: 2018
// Make sure that in pre-2021 editions we continue to parse the snippet
// `c"hello"` as an identifier followed by a (normal) string literal and
// allow the code below to compile.
// Prefixes including `c` as used by C string literals are only reserved
// in edition 2021 and onward.
//
// Consider checking out rust-2021/reserved-prefixes-migration.rs as well.
