wp_list_comments callback params

[milana_cap]

In wp-includes/class-walker-comment.php, methods comment() and html5_comment() have following order of @params: $comment, $depth, $args.

However, when you try to modify comment markup using callback argument for wp_list_comments(), order of params is $comment, $args, $depth.

Is it possible to make the same order of params?

It certainly makes sense to have semantic parameter order I totally agree. However, I'm afraid changing the callback arguments will introduce a lot of backwards incompatibility issues, and I doubt the implementors will be happy we changed the parameter order purely for the semantic purposes.

​https://github.com/search?l=PHP&q=wp_list_comments+callback%3D&type=Code&utf8=✓ here is a fuzzy GitHub search for the function call with callback parameter.

Both class methods you mentioned are protected methods, which means if we change the parameter order of those two methods, we would only need to change the current class and it's subclasses.
