#![allow(missing_docs)]
//! STDLIB-007: Array set operations (.union, .intersection, .difference)
//!
//! ROOT CAUSE: Missing set operations for arrays (treating arrays as sets)
//! SOLUTION: Implement .`union()`, .`intersection()`, .`difference()` for arrays
//!
//! EXTREME TDD: RED → GREEN → REFACTOR
//!
//! NOTE: These operate on arrays but provide set semantics (unique elements)
