//! Parser error type.
//!
//! A `ParseError` always carries a source location so errors can point at
//! the exact position in the input, independent of whether the caller
//! knows which file the source came from. The filename is added by the
//! orchestrator (main.rs) when it wraps this into the top-level error.
