Comment (by iandunn):

 The comments on [https://make.wordpress.org/core/2019/03/26/coding-
 standards-updates-for-php-5-6/ the recent coding standards proposal] also
 have some discussion about this ticket.

 In particular, the thread starting in
 [https://make.wordpress.org/core/2019/03/26/coding-standards-updates-for-
 php-5-6/#comment-35602 comment-35602]. I don't have time to dig into this
 closely, but at first glance it seems like generating a hash for a closure
 will be unreliable, since the signatures aren't unique, and change often
 in practice. Technically function names can change too, but in practice
 that's much less common.
