A proposed change to the new form factory's builder creation (to make easier)

symfony-form-factory-create.php

<?php

// current

$form = $this->get('form.factory')->create(
    new ProductType(),
    'my_form',
    array('csrf_protection' => false, 'data_class' => 'Acme\StoreBundle\Entity\Product')
);

$product = new Product();
$form->setData($product);

====================

// proposed

$product = new Product();
$form = $this->get('form.factory')->create(
    new ProductType(),
    'my_form',
    array('csrf_protection' => false, 'data' => $product)
);

=====================

// or even!

$product = new Product();
$form = $this->get('form.factory')->create(
    new ProductType(),
    $product,
    array('csrf_protection' => false, 'name' => 'my_form')
);

The first alternative makes a lot of sense to me!

I like the first alternative too - it looks like it'd be compatible with the current method, too (create() would only have to call setData())
