/**
* Filter a list of objects by executing a method across all the objects and
* filter out the ones wth empty() results. this function works just like
* @{function:ifilter}, except that it operates on a list of objects instead
* of a list of arrays.
*
* For example, to remove all objects with no children from a list, where
* 'hasChildren' is a method name, do this:
*
* mfilter($list, 'hasChildren');
*
* The optional third parameter allows you to negate the operation and filter
* out nonempty objects. To remove all objects that DO have children, do this:
*
* mfilter($list, 'hasChildren', true);
*
* @param $list array List of objects to filter.
* @param $method string A method name.
* @param $negate bool Optionally, pass true to drop objects
* which pass the filter instead of keeping them.
*
* @return array List of objects which pass the filter.
* @throws InvalidArgumentException
* @group util
*
* @deprecated
