/**
* A utility method for parsing token keyword arguments.
*
* @param array $bits A list containing remainder of the token (split by spaces)
* that is to be checked for arguments. Valid arguments will be removed
* from this list.
* @param Parser $parser
* @param bool $support_legacy If set to true ``True``, the legacy format
* ``1 as foo`` will be accepted. Otherwise, only the standard ``foo=1``
* format is allowed.
*
* @return array A dictionary of the arguments retrieved from the ``bits`` token
* list.
*
* There is no requirement for all remaining token ``bits`` to be keyword
* arguments, so the dictionary will be returned as soon as an invalid
* argument format is reached.
