//! HIR (previsouly known as descriptors) provides a high-level OO acess to Rust
//! code.
//!
//! The principal difference between HIR and syntax trees is that HIR is bound
//! to a particular crate instance. That is, it has cfg flags and features
//! applied. So, there relation between syntax and HIR is many-to-one.
