would this 'polyfill' as expected or there's more about these helpers ?
```javascript
this['@dict'] = {
keys: Object.keys,
values: function(keys){
function map(key) {
return this[key];
}
return function values(obj) {
return keys(obj).map(map, obj);
};
}(Object.keys),
entries: function(keys){
function map(key) {
return [key, this[key]];
}
return function entries(obj) {
return keys(obj).map(map, obj);
};
}(Object.keys)
};
```
Thanks
