Improvement of get_permission_lang() for use formatted string in extension

Hello

For my QTE extension i want create a new permission for each attribute created (It's easier to mange users/groups permissions with phpBB permission system instead of create mine).

So I could, in Group forum permissions, get something like this:

Can use "Resolved" attribute: yes non never
Can use "Deleted" attribute: yes non never

For that, i need to use a single formatted language string like

"Can use %s attribute"

My problem ? see:

In get_permission_lang() function:

	public function get_permission_lang($permission)

	{

		return (isset($this->permissions[$permission]['lang'])) ? $this->user->lang($this->permissions[$permission]['lang']) : $this->user->lang('ACL_' . strtoupper($permission));

	}

In my case,

$this->permissions[$permission]['lang']

should be an array. Exemple in my listener:

		$permissions += array(

			// ACP

			'f_attr_'.$row['attr_id'] => array('lang' => array('CAN_USE_ATTR', $row['attr_name']), 'cat' => 'qte'),

		);

I may be cheating by using

		$permissions += array(

			// ACP

			'f_attr_'.$row['attr_id'] => array('lang' => $this->user->lang('CAN_USE_ATTR', $row['attr_name']), 'cat' => 'qte'),

		);

but... it's an ugly trick

What do you think guys ?
