The advantage of Pascal or any full programming language over MLisp
would at first glance appear to be the availability of data types.
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.
