Comment (by dd32):

 Fun facts: `wp_rand()` only returns positive numbers (no matter the
 input), and it also doesn't care about the order of `$min` and `$max`.

 @sarciszewski Since PHP's implementation of `random_int()` has changed in
 the last few days since PHP7-RC2 was released (They've switched from PHP
 warnings to Exceptions, which your compat library deals with), I'd like to
 test this against PHP7-RC3 which is due to be released at the end of the
 week. I'm having a hard time comparing the compat library and PHP7's
 behaviours to ensure we don't have any issues at release time.
