 def map(self, selectable, base=None, **mapper_args):
 """Map a selectable directly. The class and its mapping are not cached and will be discarded once dereferenced (as of 0.6.6). :param selectable: an :func:`.expression.select` construct. :param base: a Python class which will be used as the base for the mapped class. If ``None``, the "base" argument specified by this :class:`.SQLSoup` instance's constructor will be used, which defaults to ``object``. :param mapper_args: Dictionary of arguments which will be passed directly to :func:`.orm.mapper`.
