[Docutils-develop] Accessing a node's children

[Edward L. <ed...@gr...>]

Which of the following is the preferred idiom for accessing the children 
of a docutils.nodes.Element node?  (All 3 seem to work)

 >>> for child in node: ...
 >>> for child in node.children: ...
 >>> for child in node.get_children(): ...

Similarly, which of the following is preferred for replacing the children?

 >>> node[:] = new_child_list
 >>> node.children = new_child_list
 >>> node.children[:] = new_child_list
