sqlalchemy.exc.ArgumentError raised on empty dict for info argument passed to schema.Table.init

The reason is in the following code which doesn't pop info argument from kwargs if it evaluates to false (sqlalchemy.schema.Table.init):

        if kwargs.get('info'):
            self._info = kwargs.pop('info')
        if kwargs:
            raise exc.ArgumentError(
                "Unknown arguments passed to Column: " + repr(kwargs.keys()))





>>> from sqlalchemy.schema import Column
>>> from sqlalchemy import Integer
>>> Column('test', Integer, info = {})
Traceback (most recent call last):
