<?php
$config = new Yaf_Config_Simple([
    'cache' => ['enable' => true],
    'env'   => 'development',
]);

unset($config['cache']);
var_dump(isset($config['cache']));

// Read-only configurations cannot be modified: a warning is emitted
$frozen = new Yaf_Config_Simple(['env' => 'development'], true);
