Comment:

 maksbd19 - Thanks for the suggestion!

 I agree that `WP_Query` has some limitations in the way that queries can
 be structured. In particular, query vars passed to `WP_Query` are always
 interpreted with `AND`, so that `post__in=1,2,3&post_author=5` will only
 find posts that match *both* clauses.

 In the future, it would be nice to modify `WP_Query` so that it supports
 something akin to the complex, nestable syntax of `WP_Tax_Query` and
 `WP_Meta_Query`. This will be more extensive than simply modifying the way
 that 'post__in' works. But it will also involve major reworking of
 `WP_Query`, so is some way off.
