//! Open Job Description expression language.
//!
//! This crate implements the expression language for OpenJD templates:
//! - Format string parsing and resolution (`{{Expr.Name}}` syntax)
//! - EXPR extension expression evaluation (arithmetic, conditionals, functions)
//! - Type system, runtime values, and symbol tables
//! - Range expressions and path mapping
//!
//! Uses `ruff_python_parser` for EXPR extension expression parsing.
//! See `specs/expr/parser.md` for rationale.
