SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

A typed nil stored in an interface is not nil, which can lead to surprising errors if not handled.

Core Features & Use Cases

Typed Nil Handling: Return untyped nil or handle nil receivers safely.
Practical Examples: Clear CORRECT vs WRONG patterns for common interfaces.

Quick Start

Refactor a function returning errors to ensure nil is untyped when appropriate.
