How do you wrap Laravel Eloquent ORM query scopes in parentheses when chaining?

Question

In Eloquent, I\'d like to generate this query:

SELECT * FROM table WHERE a=1 AND ( b=2 OR c=3 );

But I seem to be generating this query instead

SEE EDIT FOR FINAL ANSWER

Better than raw, use orWhere with a closure:

$model = Model::whereAIsOne()->orWhere(function($query) {
    $query->where('b', 1)->where('c', 1);
})->get();

The really unfortunate thing (and the way I ended up at this post) is that the second $query used in the closure is an instance of \Illuminate\Database\Query\Builder rather than \Illuminate\Database\Eloquent\Builder - this means that you can't use the model scopes within that closure, because Query\Builder instances don't have a reference to a model.

That said, I still think this is much more ORM-like and useful as a developer.

EDIT

Took a while to figure out, but this will work if you want to use your scopes as well:

$model = Model::whereAIsOne()->orWhere(function($query) {
    $this->newEloquentBuilder($query)->setModel($this)->whereBIsOneAndCIsOne();
})->get();

I'm actually creating a fourth scope in my code that encompasses all of this, so the $this might not work in this context - however, I find that scoping for my models is one of the most important parts of building a good system.

This definitely should be built into Eloquent - the engine has a good start, but so many features are missing.
