Comment (by scribu):

 This comes down to an inconsistency in PHP, where `__isset()` is called by
 both isset() and empty():

 {{{
 $user->user_url = '';

 isset( $user->user_url );   // true
 !empty( $user->user_url );  // false
 }}}

 For explicit calls, you have to be more verbose:

 {{{
 $user->user_url = '';

 $user->has_prop( 'user_url' );  // true

 $user->has_prop( 'user_url' ) && !empty( $user->get( 'user_url' );  //
 true
 }}}

 So, has_prop_val() sort of makes sense, but drop `__hasval()`.
