This refactoring allow to redefine every traits names by adding a trait to renamable traits :
```php
/**
 * @ORM\Entity
 */
class RenamedDeletableEntity
{
    use Model\SoftDeletable\SoftDeletable
    {
        Model\SoftDeletable\SoftDeletable::delete           as deleteTrait;
        Model\SoftDeletable\SoftDeletable::restore          as restoreTrait;
        Model\SoftDeletable\SoftDeletable::isDeleted        as isTraitDeleted;
        Model\SoftDeletable\SoftDeletable::willBeDeleted    as willTraitBeDeleted;
        Model\SoftDeletable\SoftDeletable::getDeletedAt     as getTraitDeletedAt;
        Model\SoftDeletable\SoftDeletable::setDeletedAt     as setTraitDeletedAt;
    }
```
