Correct.

I have built dynamic forms with over 300 fields. (hated it!)

I will be doing some comparisons, but regardless of who comes out on
top, the difference at runtime is not likely to be as significant as
ease of coding and maintenance. Python makes you jump through more
hoops coding-wise, but has a way of 'forcing' a discipline that
one has to conciously employ with rebol.....
Interesting enough, although I haven't seen it covered explicitly
in this list, the use of an anonymous context is more of sure-fire
way of controlling data encapsulation than is a named context or
python classes...
