        Some child of the current node had a free reference to name.
        When the child was processed, it was labelled a free
        variable.  Now that all its enclosing scope have been
        processed, the name is known to be a global or builtin.  So
        walk back down the child chain and set the name to be global
        rather than free.

        Be careful to stop if a child does not think the name is
        free.

W|j|j|�dS(s.Propagate assignment flag down to child nodes.

        The Assign node doesn't itself contains the variables being
        assigned to.  Instead, the children in node.nodes are visited
        with the assign flag set to true.  When the names occur in
        those nodes, they are marked as defs.

        Some names that occur in an assignment target are not bound by
        the assignment, e.g. a name occurring inside a slice.  The
        visitor handles these nodes specially; they do not propagate
        the assign flag to their children.
