Comment (by nacin):

 One PHP5 option is:

 `$post_id = get_post( $post_id )->ID;`

 That'll work with null, an ID, or even a post object being passed.

 I think this is a bit clearer than get_the_ID() being able to take an ID
 parameter, which seems really confusing.

 In many cases, we have functions that do these checks instead of just
 passing null etc. further down the stack, which is appropriate sometimes.
 One example is has_post_thumbnail(), which could simply pass null to
 get_post_thumbnail_id().
