SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Nil slices are valid, but encoding and iteration differ from empty slices.

Core Features & Use Cases

Append Semantics: Nil slices work with append to create a backing array.

Quick Start

Use nil for "no data" and []T{} for "empty data" in your API responses.
