This will reduce required boilerplate, but more importantly it will automatically unset variables ending on URL. This will help people needing to avoid to unset the URL variable each time a new dependency is added. It is possible that this may remove a non-download variable ending on "URL" in the future, however, the risk of this is likely much lower than the risk of someone forgetting to unset the variable.
