That would certainly be nice.
A possible middle ground would be a way to specify a list of events
and/or controls which a given control would "watch" for purposes of
Dynamic* evaluation. So if my button depended on the value in a certain
spinner control, I could pass "Watch=[thatSpinner]" to the button's
constructor, and it would update itself whenever the thatSpinner object
changed.
