    If I may, here’s my patch – you can read or ignore/delete the long comments. I think if we delete the verbose comments, my version would be somewhat shorter and easier to read.

    The author actually wrote the original line of code as an elegant way to get two variables $module and $params from the function parameter. He even saved some memory by overwriting the function parameter $module – not that I agree with this kind of coding style.
