This is the sort of thing that Proto's tree transformations handle
naturally, but Proto transforms only work when the tree nodes can be 
differentiated at compile time. Perhaps there is some synergy between 
these two libraries.

I'm working on the documentation for Proto's new tree transformation 
framework right now. Dan, we should talk.
