Drupal - Saving custom fields for nodes and users

I haven't done this with user_save() before but if it follows convention from the rest of the system (which is likely) it'll be like this:

$values = array(
  'name' => $name, 
  'pass' => $password,  
  'mail' => $email, 
  'status'=>1,
  'field_foobar' => array(
    LANGUAGE_NONE => array(
      0 => array(
        'value' => $field_value
      )
    )
  )
);

$newUser = user_save('', $values);

In fact there are a few examples further down the page in the user_save() docs confirming this method is the right one.
