 """Parse an assignment target. As Jinja2 allows assignments to tuples, this function can parse all allowed assignment targets. Per default assignments to tuples are parsed, that can be disable however by setting `with_tuple` to `False`. If only assignments to names are wanted `name_only` can be set to `True`. The `extra_end_rules` parameter is forwarded to the tuple parsing function. If `with_namespace` is enabled, a namespace assignment may be parsed. """
