Comment (by obenland):

 Replying to [comment:17 ocean90]:
 > The function declaration should be outside of `wp_title()` otherwise it
 will lead to a "cannot redeclare" fatal error if `wp_title()` gets called
 twice.

 Good point, I shall update the patch.

 > Wasn't there a suggestion to make `wp_title()` a wrapper for
 `wp_get_document_title()` somewhere?

 Maybe on [https://make.wordpress.org/core/2015/10/20/document-title-
 in-4-4/ the make/core post]? I'm not sure it would help with maintaining
 back compat for the filters in there. We could maintain it for `wp_title`
 but probably not for `wp_title_parts` unless I'm missing something.
