Comment(by ericmann):

 I'd much rather focus on one of two options:

 '''1. Make the original functions more flexible.'''

 Right now, functions like `get_the_title()` take in a post ID and return a
 title.  If it could take in ''either'' a post ID or a post slug, this
 would be more flexible and powerful.

 '''2. Use a `get_post_by` instead'''

 The return of a `get_post_by` can be an object or associative array with
 most of the data you need.  Responding to your specific examples:

 {{{
 // title of the page with slug "gallery":
 echo get_post_by_slug( 'gallery' )->the_title;

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

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

 IMO Building quick one-off functions to return simple data will just bog
 things down and cause problems.  If you take an object-oriented approach
 you can store most of this data in an object and just reference it when
 needed.
