Yeah, kinda like taking darcs' advanced diff format (token
replacement, etc) to the limit -- as long as you can provide a lens
for a given file format, darcs would be able to do much more
intelligent diff/patch/merge operations on the tree structure instead
of a big pile of text lines.

Imagine parse-tree level source code diffing... ;)
