//! TDD Test: Enum variant constructors with string literal arguments
//!
//! Bug: When constructing an enum variant that takes a String field with a
//! string literal (e.g., GameEvent::ItemPickup("Health Potion")), the codegen
//! generates `GameEvent::ItemPickup("Health Potion")` without adding `.to_string()`.
//! Rust expects `String`, not `&str`.
//!
//! Expected: `GameEvent::ItemPickup("Health Potion".to_string())`
//! Actual:   `GameEvent::ItemPickup("Health Potion")`
