explicitly named (usually the one on the left of the :: operator); in case
of non static method calls, it is the class of the object.
A "forwarding call" is a static one that is introduced by self::, parent::,
static::, or, if going up in the class hierarchy, forward_static_call().
The function get_called_class() can be used to retrieve a string with the name
of the called class and static:: introduces its scope.
