示例1: Iterate
// No `ini` binding yet. Hdf still takes precedence but will be removed
// once we have made all options ini-aware. All new settings should
// use the ini path of this method (i.e., pass a bogus Hdf or keep it null)
void Config::Iterate(std::function<void (const IniSettingMap&,
const Hdf&,
const std::string&)> cb,
const IniSettingMap &ini, const Hdf& config,
const std::string &name,
const bool prepend_hhvm /* = true */) {
// We shouldn't be passing a leaf here. That's why name is not
// optional.
assert(!name.empty());
