Phase 3 - Result/Option Integration: Implementation Summary

1. FULL GENERIC ENUM SYSTEM (15-20 hours)
   - Parser support for enum Result<T, E> { Ok(T), Err(E) } syntax
   - Generic type parameter substitution and inference
   - Works for ALL enums, not just Result/Option

2. CONFIGURABLE NONE TYPE INFERENCE (3-4 hours)
   - Add none_type_inference option to dingo.toml (explicit | context)
   - Explicit mode: Requires type annotation (let x: Option<int> = None)
   - Context mode: Infers from assignment/return type (default)

3. COMPREHENSIVE HELPER METHODS (8-10 hours)
   - Result<T, E>: Unwrap, UnwrapOr, Map, AndThen, MapErr, etc. (8 methods)
   - Option<T>: Unwrap, UnwrapOr, Map, Filter, IsSomeAnd, And, Or, etc. (10 methods)
   - All methods fully tested and documented

4. TIMELINE: 33-44 hours (4-6 days focused work)
   - Higher complexity accepted for better long-term foundation
   - Enables 9 golden tests (5 result + 4 option)
   - Provides Rust-like ergonomics with zero runtime overhead
