docs: def merge_links_from(self, other_node, merge_same_value_targets=False):
          """
          Merge links from another node with ``self.link_list``.
  
          Copy links from another node, merging when copied links point to a
          node which this already links to.
  
          Args:
              other_node (Node): The node to merge links from
              merge_same_value_targets (bool): Whether or not to merge links
                  whose targets have the same value (but are not necessarily
                  the same ``Node``). If False, links will only be merged
                  when ``link_in_other.target == link_in_self.target``. If True,
                  links will be merged when
                  ``link_in_other.target.value == link_in_self.target.value``
  
          Returns: None
  
          Example:

              >>> node_2 = Node('Two')
              >>> node_1.add_link(node_1, 1)
              >>> node_1.add_link(node_2, 3)
              >>> node_2.add_link(node_1, 4)
              >>> node_1.merge_links_from(node_2)
              >>> print(node_1)
