'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.'
