Ray,
a system prone to constraints is necessary if you think about an activity that
should proceed in a criticize/refine way, like design activity.
But, of course, the system always imposes some constraints to the user, because
it works only in a well-defined domain. Anyway, in the domain the user should be
freed from system constraint as much as possible.

I've read something about that from Mary Lou Maher. She was presenting some
different approach to design, including shape grammars (AI Magazine, vol 11,
no 4, winter 1990). I think that shape grammars could be used in a well defined
particular context. To manage context maybe it could be used something like
case-based reasoning. It's a little like the relation between mixed frame- and
rule- expert system.
What is your opinion?
