//! Rust language definition.
//!
//! The extra rules exist because the generic scanner would get three things
//! wrong: attributes look like comments-that-are-not, raw strings ignore
//! backslash escapes, and a lifetime `'a` looks like the start of a character
//! literal. Putting the character-literal pattern *before* the lifetime pattern
//! is what disambiguates `'a'` from `'a`.
