Could you add a paragraph or two explaining the reasons for choosing this
particular proposal?
Some examples of what I would like to read:
 - why we can't do preg_replace_callback($array_of_regexes,
$array_of_callbacks, $subject)
 - why not preg_replace_callback($array_of_regex_to_callback_pairs,
$subject)
 - why not pass the regex used to the callback, as per Laruence's earlier
RFC

And give a few links to historical discussions in the same sort of area?
E.g Laruence's RFC: https://wiki.php.net/rfc/second_arg_to_preg_callback an=
d
its discussion thread (http://php.markmail.org/thread/qwiyq5o2vwlbdczq).
