I would like to suggest some additions to Element:

walk: A generator that walks a tree in depth-first order. I think this
     is the same as "getiterator" but the docs are confusing.

reverse_walk: Like walk but in the reverse order.

walkaround: Walks around the outside of a tree. Each non-terminal node
     is visited twice. Each node should have a attribute whose values can
     be NONE, DONE, FIRST, SECOND, and LEAF.

kill: Removes a node from a tree. It is replaced by its children.

prettyprint: Prints a tree with each node indented according to its
     depth.
