//! Defines the AST nodes that describe the syntax of the macro.
//!
//! The convention is that AST elements are themselves immutable and their mutable metadata is
//! stored in a separate [`AstMetadata`] structure:
//!
//! - Each AST element has a unique ID (of type [`NodeId`]).
//! - [`AstMetadata`] allows to reference metadata by the ID of the related AST-elements.
