 Replying to [comment:8 mlajo]:
 > This is not consistent with mt_rand and contra intuitive.

 What I meant by consistency is that both `mt_rand()` and `wp_rand()`, when
 called without any parameters, return a random number. But you're right
 that the results for `mt_rand( 0, 0 )` and `wp_rand( 0, 0 )` are

 On second thought, maybe we could still fix it, see
 [attachment:55194.diff]. This would need a unit test and security review.

 > It caused lots of trouble in our code until we pinpoint it to this

 Just out of curiousity, what would be the use case for a `wp_rand( 0, 0 )`
