// DISABLED: This test uses old REPL API that was refactored
//
// ROOT CAUSE: Test relies on methods that no longer exist:
// - Repl::checkpoint() → removed during state management refactor
// - Repl::restore_checkpoint() → removed during state management refactor
// - Value::Char variant → not implemented in current Value enum
//
// FIX REQUIRED: Rewrite to use current ruchy::runtime::repl::Repl API
// - Replace checkpoint/restore with current state management approach
// - Remove Value::Char tests or implement Char variant in Value enum
// - Update to use current Repl::eval() API
//
// EFFORT: ~2-3 hours to rewrite
// PRIORITY: High - Sprint 1 regression tests
// TICKET: Create QUALITY-XXX for REPL test modernization
