//! TDD: int vs usize comparison type inference
//!
//! BUG: Comparing int (i64) with usize causes E0308
//!
//! Example:
//! ```windjammer
//! if self.index >= self.entities.len() {
//!     // self.index is i64, len() returns usize
//! }
//! ```
//!
//! EXPECTED: Auto-cast to make comparison work
//! ACTUAL: E0308 mismatched types
