Comment (by SergeyBiryukov):

 In [changeset:"60330" 60330]:
 {{{
 #!CommitTicketReference repository="" revision="60330"
 Docs: Correct parameter and return types for some comment functions.

 This commit corrects some parameter type issues concerning arrays. More
 specifically:

 * `separate_comments()` now correctly indicates that it returns an array
 of `WP_Comment` objects, keyed by their string types.
 * `_close_comments_for_old_posts()` now correctly indicates that it both
 takes and returns an array of `WP_Post` objects.

 Follow-up to [8892], [8897], [8949], [32587], [42876].

 Props justlevine, johnbillion.
