Constant in a class

Hey there

I wonder how I could access a constant in a class/library from outside through CI's loading mechanics:

Code:

[...]
//library lib_test.php
const SOME_CONSTANT    = 0;

Now, in a controller, this doesn't work:

Code:

$this->load->library('lib_test'));
echo $this->lib_test::CONSTANT;    //Parse-error
echo $this->lib_test->CONSTANT;    //No parse-error, but neither a result

Any suggestion how to access constants (or class-vars)?
