How to extend blade syntax with your package

In Laravel someone can easily write 

```
Blade::extend(function($value) {
    return preg_replace('/\@define(.+)/', '<?php ${1}; ?>', $value);
});
```

for custom syntax

```
@define $i = 1
```

Is this possible with your package and how? Method `extend` exists only in class `Illuminate\View\Compilers\BladeCompiler.php`
