Richard,
I was also concerned about the legacy apps. My first thought was to
allow "load by reference" for some period of time (for example all
shipments of Rev. delivered after January 2007 would require the new
behavior). But it may be that only a very small group of current Rev
programmers are even aware of this feature. I'd like to hear from them
before finalizing any recommendations.
I also believe the "load stack" command would address Robert's
concerns.
Can we kill "destroyStack" in my lifetime?

If I understand Paul's suggestion correctly, I believe that's covered
under his request for a "load" command.
His thinking is not unlike something we all go through learning Rev:
in any other app closing a window ultimately purges the data presented
in it from memory.
As much as I like (and often rely on) the current stay-resident
behavior I wouldn't mind if it were optional, with the default being
the more intuitive purge.
Of course backward compatibility is a whole other issue, so at best we
might hope for some global flag to allow the old behavior to be
sustained for legacy stacks without requiring an explicit "load".
