// Test: HashMap/HashSet in comments should NOT trigger auto-import
//
// Bug: The compiler uses `format!("{:?}", program)` to scan for HashMap/HashSet usage,
// which matches text in comments (e.g., "HashMap-like"). This causes
// `use std::collections::HashMap;` to be emitted even when no HashMap is used in code.
//
// Root cause: Debug representation includes comment text, so string matching on it
// produces false positives.
//
// Fix: Walk the AST properly to detect actual type usage, not debug text.
