 Since 2.9-ish there has been an emphasis on querying objects by slug, for
 various reasons (especially terms).

 Unfortunately, many template functions require either that one be in the
 Loop or explicitly pass a post object ID.  Currently, to get an object's
 ID in order to pass it to one of the functions, you have to go through
 several steps that include querying the object and checking for the
 necessary properties of the desired result.

 '''Proposed New Function'''

 int '''get_id_by_name''' ( string ''$name_or_slug'' )

 Examples:

 {{{
 // title of the page with slug "gallery":
 echo get_the_title( get_id_by_name( 'gallery' ) );

 // custom field for post titled "My Day at the Beach"
 echo get_post_meta( get_id_by_name( 'my-day-at-the-beach' ), 'photos-url',
 true );

 // images attached to the "Employees" page:
 $images = get_children( array('post_parent' => get_id_by_name( 'employees'
 ), 'post_status' => 'inherit', 'post_type' => 'attachment',
 'post_mime_type' => 'image' ) );
