MadAppGang/dingo: A meta-language for Go that adds Result types, error propagation (?), and pattern matching while maintaining 100% Go ecosystem compatibility

• ✅ 67% less error handling boilerplate — ? operator instead of 47 if err != nil blocks
• ✅ 78% code reduction with sum types — Rust-style enums that just work
• ✅ Zero nil pointer panics — Option types that the compiler enforces
• ✅ Pattern matching — Exhaustive, type-safe, impossible to mess up
• ✅ Same performance — Transpiles to clean Go, zero runtime overhead
