However, the text in the buffer can be structured to simulate any sort of data structure you might desire. I am not at all convinced that general data types would be useful. In fact, my guess is that they will make editor procedures less, rather than more, understandable. In addition, there are characteristics of the way many data types that we would like to add are interfaced with the implementation which make user extension difficult -- witness the addition of "marker" data types to MLisp.
