I would like to be able to interpolate a Zend_Db_Select object into a query and have it be rendered as a string, and wrapped in parentheses so it can be a subquery:

<pre class="highlight">
$select = $db->select()
->from( $db->select()->from('subqueryTable') );

Should produce:

<pre class="highlight">
FROM (SELECT * FROM "subqueryTable")

<pre class="highlight">
$db->quoteInto('WHERE foo IN ?', $db->select()->from('subqueryTable'));

Should produce:

<pre class="highlight">
WHERE foo IN (SELECT * FROM "subqueryTable")

So we need that the quote() method and the quoteIdentifier() method check for an object of type Zend_Db_Select, and turn it into:

<pre class="highlight">
new Zend_Db_Expr( '(' . $selectObject->__toString() . ')' )

That should handle both cases.
