        selector function to incorporate the corresponding source for each item

        Note: This method uses deferred execution.

        Args:
            collection_selector: A unary function mapping each element of the
                source iterable into an intermediate sequence. The single
                argument of the collection_selector is the value of an element
                from the source sequence. The return value should be an
                iterable derived from that element value. The default
                collection_selector, which is the identity function, assumes
                that each element of the source sequence is itself iterable.

            result_selector:
                An optional binary function mapping the elements in the
                flattened intermediate sequence together with their
                corresponding source elements to elements of the result
                sequence. The two positional arguments of the result_selector
                are, first the source element corresponding to an element from
                the intermediate sequence, and second the actual element from
                the intermediate sequence. The return value should be the
                corresponding value in the result sequence. If no
                result_selector function is provided, the elements of the
                result sequence are KeyedElement namedtuples.

        Returns:
            A Queryable over a generated sequence whose elements are the result
            of applying the one-to-many collection_selector to each element of
            the source sequence, concatenating the results into an intermediate
            sequence, and then mapping each of those elements through the
            result_selector which incorporates the corresponding source element
            into the result sequence.

        Raises:
            ValueError: If this Queryable has been closed.
            TypeError: If projector or selector are not callable.
