 Replying to [comment:1 filosofo]:
 > Don't you think it seems reasonable to expect a function prefixed with
 "is_" to have a boolean return value?  That's what the built-in PHP
 functions do, and all of the other WP functions (as far as I know).

 It does seem reasonable, but this patch still allows is_user_logged_in()
 to evaluate to true or false, as it either returns false or a user ID that
 evaluates to true. It just provides a little more functionality this way.

 > And it especially makes sense in light of that other ticket you opened
 that shows PHP is inconsistent across versions in comparing variables of
 differing types.

 Actually, we found that PHP was consistent and documented, and it was only
 with regards to comparing a string to 0. See #11391. So this isn't an
 issue, especially since this function would never return 0 or a string.
