Accept 'meta_query' parameter in `WP_Tax_Query`

[Hrohh]

It would by possible to extend like that?

<?php
$args = array(
        'post_type' => 'post',
        'tax_query' => array(
                array(
                        'taxonomy'      => 'people',
                        'field'         => 'meta',
                        'meta_query'    => array(
                                array(
                                        'key' => 'map',
                                        'compare' => 'EXIST'
                                )
                        )
                ),
        ),
);
$query = new WP_Query( $args );
?>

Hi @Hrohh - This is a very interesting idea. It's more of an enhancement request for WP_Tax_Query than for WP_Meta_Query, so I'm going to recategorize the ticket as appropriate.

I like this idea, but we'll need to see at least a proof-of-concept patch to move forward with it. There are a number of questions I've got about how queries will be constructed and cacheability - whether we should use IN ( results of a WP_Term_Query ) or a separate JOIN - that will only be clearer once we've got some patches to benchmark.
