//! This module provides implementations for converting the automatic Parol AST
//! (Abstract Syntax Tree) into the internal AST representation (`crate::ir::ast`).
//!
//! The module includes various `TryFrom` implementations for converting between
//! the `modelica_grammar_trait` types and the internal `ir::ast` types.
