Comment (by hellofromTonya):

 In [changeset:"51657" 51657]:
 {{{
 #!CommitTicketReference repository="" revision="51657"
 Coding Standards: Use static closures when not using `$this`.

 When a closure does not use `$this`, it can be made `static` for improved
 performance.

 Static closures are supported in PHP since PHP 5.4. ​

 Props jrf, hellofromTonya, swissspidy, SergeyBiryukov.
 See #53359.
