// Phase 224-B: MethodCall lowering test - s.length() in loop condition
//
// Test case: Simple loop using s.length() in condition
// Expected: MethodCall should be lowered to BoxCall instruction
//
// Pattern 1: Simple while loop (no break, no continue)

static box Main {
    main() {
        local s = "Hello"
        local i = 0

        // Pattern 1 loop with MethodCall in condition
        loop(i < s.length()) {
            i = i + 1
        }

        // Output result
        print("i = " + i)
        return i
