Thanks, that's really helpful. I like the concept of integrated rank
support. Using an argument of i.30 40 50 there is a noticably shorter
response time if it is prefixed by the second verb. Why shouldn't integrated
rank support be extended to the first verb? I guess it's just a matter of
interpreter sophistication, and no doubt there are pros and cons to every
piece of added complexity.
