Module error 

Error types and display formatting for parse errors.

This module provides structured error types for the lexer and parser, with rich diagnostic output including:

• Source location with line/column numbers
• Syntax-highlighted error messages
• Socratic explanations for common mistakes
• Spelling suggestions for unknown words

Error Display

Errors can be displayed with source context using ParseError::display_with_source, which produces rustc-style error output with underlined spans.

Structs

A parse error with location information.

Enums

Functions

describe_token

A human reading of a token for error prose — never the raw Debug name. “a comma (‘,’)” teaches; “Comma” is compiler debris.
