Hi,

Stan, did you actually try this out?  According to my checkout of CVS,
you're wrong.  Try this script:

<?php
namespace one;
class one {
static function hi(){echo "hi\n";}
}
one::hi();
namespace two;
use one::one;
one::hi();
namespace three;
one::hi();
?>

The output is:

hi
hi

Fatal error: Class 'three::one' not found in
/home/user/workspace/php5_func/test.php on line 11
