Hindsight is 20/20, but I sure wish that someone had seen the wisdom of
creating a new class of array storage that had the following
characteristics.
1. Disk-based so it didn't impact partition memory
2. Temporary (automatically was killed when the process terminated)
3. Supported nodes with WORM features (not required for all nodes of
the storage)
4. Supported the idea of private and public branches of nodes
The SSVN concept seems like it would be a great way to implement the
above. Maybe there is no wisdom in what I described.... but either way,
it is too late for VistA. The best we can do is instill consistent
programming practices to maintain backward compatibility, right?

I guess the subject line says it all. Can anyone make a case for
supporting dynamic scoping rules?
I realize that my previous post on this topic was a little unclear
about the nature of dynamic vs. static scoping. Variables withing a
nested block can hide variables by the same name in an enclosing block
under static scoping rules, too. A simplke example of something that
does require dynamic scoping is
S D=4
W !,$$INC(1)
Q
;
INC(PI) ;
Q PI+D
Under static scoping rules, this code wouldn't even compile, because
whether or D is within scope in the body of INC depens on whether or
not it was bound when the call was made.
