What potential pitfalls should be considered when using PHP Boost for performance optimization?

Potential pitfalls when using PHP Boost for performance optimization include: 1. Over-optimization leading to reduced code readability and maintainability. 2. Dependency on specific PHP versions or configurations that may limit portability. 3. Potential for unintended side effects or bugs due to aggressive optimization techniques.

// Example code snippet demonstrating a potential pitfall of over-optimization in PHP Boost

// Before optimization
function calculate_sum($array) {
    $sum = 0;
    foreach ($array as $value) {
        $sum += $value;
    }
    return $sum;
}

// After optimization
function calculate_sum($array) {
    return array_sum($array);
}
