## Comparison

```php
// returns false
if ($action === Action::VIEW()) {
// ...
}
```

```php
// returns true
if ($action == Action::VIEW()) {
// ...
}

// true
if ($action->equals(Action::VIEW())) {
// ...
}
```

php-enums are not singletons so when doing strict comparison, you are comparing equality of _objects_, not values.
