示例1: testSetScopeSafeVariable
/**
* Test for issue #12285
* Variables set by functions handled by eZObjectForwarder (like attribute_view_gui) are not scope safe.
* The patch for this issue ensures that, if requested, a template variable can be backed up in a safe namespace
* (same var name but different namespace), so that it can't be overridden
* @param string $varName
* @param string $val
* @param string $namespace
* @link http://issues.ez.no/12285
* @group issue12285
